The Essay Exam

Organization and neatness have merit

Before writing out the exam: ▪ Write down their key words, listings, etc, as they are fresh in your mind. Otherwise these ideas may be blocked (or be unavailable) when the time comes to write the later questions. This will reduce "clutching" or panic (anxiety, actually fear which disrupts thoughts).

Set up a time schedule to answer each question and to review/edit all questions ▪ If six questions are to be answered in sixty minutes, allow yourself only seven minutes for each ▪ If questions are "weighted", prioritize that into your time allocation for each question ▪ When the time is up for one question, stop writing, leave space, and begin the next question. The incomplete answers can be completed during the review time ▪ Six incomplete answers will usually receive more credit than three, complete ones

Read through the questions once and note if you have any choice in answering questions ▪ Pay attention to how the question is phrased, or to the "directives", or words such as "compare", "contrast", "criticize", etc. See their definitions in "Essay terms" ▪ Answers will come to mind immediately for some questions

Before attempting to answer a question, put it in your own words ▪ Now compare your version with the original. Do they mean the same thing? If they don't, you've misread the question. You'll be surprised how often they don't agree.

Think before you write:

Make a brief outline for each question

Number the items in the order you will discuss them ▪ Get right to the point State your main point in the first sentence Use your first paragraph to provide an overview of your essay. Use the rest of your essay to discuss these points in more detail. Back up your points with specific information,…...

...Acceleration Graphs Instructions to Recreate Graph 3 Analysis of Newton’s 3 Laws of Motion Part 2: Scenario C Graph, Force Diagrams, Regions Explanation of Graph Self-Assessment Summary Report on Motion PHS 100 Lab 552 26 March 2013 Region 1: The fan cart is at a constant position. As you can see, the fan cart is set at a constant position of 2.0 meters away from the motion detector. Velocity and acceleration are zero as the cart is not moving. Region 2: A change in motion is occurring. As the cart begins to move, the position of the cart moves closer to the detector. Velocity and acceleration are at a negative slope because the direction is changed from no movement to movement. Region 3: The fan cart is moving at a constant speed and direction towards the detector. Slope for velocity becomes positive as the speed is now greater than zero. Acceleration is constant. Region 4: The fan cart has now moved to a closer position to the motion detector. Velocity and Acceleration is at zero because there is no movement. Regions of Graph 3: Region 1- The fan cart is at a constant position as it is not moving. Since the position is just less than 2 meters away from the detector, we know the fan cart is not directly in front of the motion detector. There is no acceleration. Region 2- The fan cart begins to gradually accelerate towards the motion detector. While the position remains constant, the velocity is changed in......

...Abstract Objective The objective of this experiment was to familiarize ourselves with constant acceleration equations, and to better understand the horizontal and vertical components of a projectile in free fall. Procedure In this experiment we used a PASCO projectile launcher, a photogate and the PASCO equipment to calculate the initial velocity of a ball that we launched off of a table. With this measurement we were able to use constant acceleration equations to calculate the range and the time of flight of the ball. We then used a “time of flight accessory” to obtain a measured value of time of flight. We compared our measured findings to our calculated findings to see the difference. Finally we created four graphs that illustrated horizontal and vertical velocity, as well as horizontal and vertical position all compared to time. Data Our ball was in flight for about .48 s and had an initial velocity of 3.14 m/s. In our vertical velocity verse time graph, I calculated the slope of the line to be 9.8 m/s^2. I am very happy with this result because it is very close to the real acceleration of gravity. Finally, our measured value of time of flight and calculated value deviated by .006s. This was also really cool to see. Sources of Error We did not take air resistance into consideration in this lab. As the ball is flying through the air, it is being slowed down by the air drag. This could have made our measured value of time of flight slower than......

...Range of motion is the distance and direction a joint can move between the flexed position and the extended position while properly attached to the body. Range of motion exercises refers to the act of attempting to increase the distances by stretching from flexion to extension for physiological gain. Each specific joint has a normal range of motion that is expressed in degrees. Goniometer and Inclinometer are some of the devices used to measure range of motion in the joints of the body. As measurement results will vary by the degree of resistance, two levels of range of motion results are usually recorded. Limited range of motion refers to a reduction in a joints’ ability to move. This may be due to a mechanical problem with the specific joint or due to injury or diseases such as arthritis. Pain, swelling and stiffness associated with arthritis can limit the range of motion of a particular joint and impair function and ability to perform usual daily activities. Range of motion exercises is ordered by a doctor and can help keep the joints and muscles healthy. These exercises are most convenient for those who spend plenty of time in bed or a wheelchair. They help prevent joints such as knees and elbows from getting locked and stiff. Range of motion exercises are not for building muscles. There are three types of range of motion exercises. Passive Range of Motion: The therapist or equipment moves the joint through the range of motion with no effort from the......

...Lab # 111 “Projectile Motion” Objectives : The purpose of this lab is to understand projectile motion in two dimensions and apply linear motion equations to solve the problem. Also to predict where a given size bullet to be placed in horizontal direction to leaving table. In addition to that measure the range of projectile leaving table at an angle, and use the value to predict where the projectile bullet to strike at floor. Theory : To predict where bullet will land on the floor when lunched from the mini launcher from a table at an angle, but to do that first we need to determine the velocity of the bullet and to determine by launching the bullet horizontally from the table and measuring the vertical and horizontal distances through distance that the bullet travels. Then the initial velocity can be used to calculate where the bullet will land when the bullet lunched from the mini launcher at an angle. Horizontally lunched bullet at θ=0 off a table with an initial speed, vo, the horizontal distance travelled by the bullet and the vertical distance of the bullet drop in time t describe: x= v0t (1) y=v0yt+12gt2 (2) Now we can determine the initial velocity of the bullet by measuring x and y. where y = 0, therefore, the time of the bullet can be found by equation: t= 2yg, Where g = 9.8 (3) Now, to guess the range of the bullet, x, at and angle, θ, above horizontal, we guess the time of the bullet using vertical motion equation:......

...Experiment 4 Projectile Motion Introduction We examined projectile motion by observing a ball rolling down then leaving the ramp, thus becoming a projectile with a horizontal initial velocity. We measured the horizontal initial velocity using the photogate and computer. We measured the horizontal and vertical distances that the projectile traveled from the end of the ramp to when it hit the floor my using a meter stick to measure Experimental Set-Up In our experiment, we used the following: ramp, photogate, steal ball, plumb bob, meter stick, and vernier caliper. Experimental Procedure 1.At the edge of our lab table, we prepared the ramp. 2.Exactly below the launch point, we marked a point on the floor by using the plumb bob. 3.We determined the vertical distance that the ball fell (mm) from when it was launched from the ramp and fell on the floor. We then entered this in our data table. 4.We positioned a piece of paper on the floor to where the ball would land. We put the carbon paper above the paper and taped them to the floor. 5.We fixed the photogate so the ball rolled out and the light beam was blocked and unblocked. The photogate was plugged into the LabPro Dig/Sonic1 port. 6.We opened up the One Gate Timing from the Logger Pro folder. 7.We measured the diameter of the ball with the vernier caliper and recorded it in the computer so that it could calculate the ball’s launch velocity. 8.We launched the ball from a specific height from the ramp so that the......

...Fundamentals of Fluid Mechanics Fluid mechanics is the study of fluids and the forces on them. (Fluids include liquids, gases, and plasmas.) Fluid mechanics can be divided into fluid kinematics, the study of fluid motion, and fluid dynamics, the study of the effect of forces on fluid motion, which can further be divided into fluid statics, the study of fluids at rest, and fluid kinetics, the study of fluids in motion. Fluid mechanics is very important to engineers when observing flow in pipes, viscous effects of fluids, and the forces that act on a fluid. As a student, I am suppose to demonstrate an adequate understanding of many properties involved fluid mechanics. Some learning outcomes that must be accomplished by taking this class are: * Demonstrate understanding of fluid mechanics fundamentals, fluid and flow properties such as compressibility, viscosity, buoyancy, hydrostatic pressure and forces on surfaces * Apply Bernoulli equation to solve problems in fluid mechanics * Solve fluid mechanics problem using control volume analysis using conservation of mass, energy equation and irreversible flow * Use differential analysis of fluid flow, potential flow theory, viscous flow, Navier Stokes equations to solve problems * Perform modeling and similitude using Buckingham Pi theorem, correlation of experimental data. * Analyze flow in pipes to determine laminar and turbulent flow behaviors. * Apply energy and momentum equations to......

...Projectile motion Projectile motion is defined as the motion of a particle through a region of space where it is subject to constant acceleration. An object moving through the air near the surface of the earth is subject to the constant gravitational acceleration g, directed downward. If no other forces are acting on the object, i.e. if the object does not have a propulsion system and we neglect air resistance, then the motion of the object is projectile motion. Trajectory: This refers to the path the projectile follows when fired from a gun, or a bat, or someone throwing the object, or whatever its source of motion is. In our demonstrations, projectiles will follow curved paths that will be interesting to observe. Projectile: Any object which is given some velocity and then left to fly through the gravitational field with only the gravitational force acting on it. An example is a baseball hit by a bat, a basketball shot toward a basket, a bullet fired from a gun, etc. Range: The horizontal distance a projectile is fired. How far it moves away from whatever gave it its horizontal motion. We will be firing a projectile at an angle with the horizontal; it will arc upward and outward. How far outward it goes is the range of the projectile. Any projectile thrown, such as a ball, can be considered to have a vertical and horizontal velocity component. Throughout the path of the projectile, change occurs only in the vertical direction due to the influence of gravity...

...A projectile is a body in free fall that is subject only to the forces of gravity (9.81ms‾²) and air resistance (Webster). It was Galileo who first accurately described projectile motion. He showed that it could be understood by analyzing the horizontal and vertical components separately. No one had done this prior to Galileo. People use to think that when something is shot in the air it goes in the air and some how hit something and explode, before Galileo which followed largely Aristotelian lines but incorporating a later theory of "impetus," which maintained that an object shot from a cannon, for example, followed a straight line until it "lost its impetus," at which point it fell abruptly to the ground. Later, simply by more careful observation, it was realized that projectiles actually follow a curved path. Yet no one knew what that path was, until Galileo. There was yet another brilliant insight that led Galileo to his most astounding conclusion about projectile motion. First of all, he reasoned that a projectile is not only influenced by one motion, but by two. The motion that acts vertically is the force of gravity, and this pulls an object towards the earth at 9.8 meters per second. But while gravity is pulling the object down, the projectile is also moving forward, horizontally at the same time. And this horizontal motion is uniform and constant according to Galileo's principle of inertia. He was indeed able to show that a projectile is controlled by two......
