LAW TONG &AIDEN 2013/9/23 AP PHYSICS B Mr. Moss THE LAB OF ATWOOD Procedure: The purpose of this experiment was to verify the predictions of Newton’s Law for an Atwood machine‚ a simple machine constructed by hanging two different masses and from a string passing over pulleys and observing their acceleration.. Newton’s Law predicts that the acceleration should be proportional to the difference between the masses and proportional to their sum‚ where = 9.8 m/s2 is the

Experiment 1.7: Graphical Analysis of Motion Introduction To graphically analyze motion‚ two graphs are commonly used: Displacement vs. Time and Velocity vs. Time. These two graphs provide significant information about motion including distance/displacement‚ speed/velocity‚ and acceleration. The displacement and acceleration of a moving body can be obtained from its Velocity vs. Time graph by respectively finding the area and the slope of the graph. Data Tables – Part I Displacement

Name Noah Meador___ Motion in 2D Simulation Go to http://phet.colorado.edu/simulations/sims.php?sim=Motion_in_2D and click on Run Now. 1) Once the simulation opens‚ click on ‘Show Both’ for Velocity and Acceleration at the top of the page. Now click and drag the red ball around the screen. Make 3 observations about the blue and green arrows (also called vectors) as you drag the ball around. 1. The green line points in the direction that the ball is going to go 2. The blue line changes the

each other. When I move the ball one direction‚ both of the vectors move the same direction i.e. move right‚ the arrows move right. Then when I exert stopping force onto the ball‚ the green continues to move with the same direction while the blue moves the opposite direction. The slower I move the ball‚ the smaller the vectors are and conversely‚ the faster I move the ball‚ the larger the vectors are. 2) Which color vector (arrow) represents velocity and which one represents acceleration?

Physics Pre-AP Projectile Motion Lab Report Purpose The purpose of this lab was to determine how angle and gravity affects velocity and range. Procedure Materials Projectile launcher Marble Two measuring sticks Tin foil Pencil Procedure Set the angle of the projectile launcher to 30 degrees (make sure that the bottom of the launcher is even with the desk). Put the marble inside the projectile launcher‚ and using the pencil‚ push the marble inside until you hear one click. Retract the

Show your data‚ graphs‚ and calculations that support your strategy. The time it takes a pendulum to complete one back-and-forth swing‚ called the pendulum’s period‚ depends only on the pendulum’s length and the value of gravity. In an experiment‚ an experimenter can easily manipulate a pendulum’s length. The value of gravity cannot be manipulated. The best

during the experiment‚ nor were any windows opened or closed‚ ensuring that the results would not be affected from air currents pushing or angling the car. Procedure: 1. Using a meter stick‚ one person measure and record the height of incline plane at its highest point from the table. Then‚ using a meter stick‚ one person measure and record the length of the incline plane and the level horizontal track. 2. Without the use of ticker tape or a spark timer‚ place the car at the top of the incline plane
