Measurements of velocity and mass of two objects colliding support the conservation of linear momentum The dynamics of different masses distinguish velocity values experimentally Video recordings of two colliding masses can be manipulated to extract frames displaying distance verses time Computer software enables us to derive the velocity Different masses were tested to determine an increase decrease or equaleffect From this data we ultimately derive the momentum of each cart and test the Law of Linear momentum The following trials were measured1 An elastic collision with a cart moving at constant speed with a cart of2 An elastic collision with a car moving at constant speed and a cart ofone-third the mass originally at rest3 An elastic collision with a cart of three times the mass originally at4 An inelastic collision with a cart moving at constant speed and a cartof two times the mass originally at rest1 Set-up camera according to the correct settings noted in 34 pp 192 Establish four points of reference visible in the camera frame Place the initial motionless cart at the second reference point from the end opposite of the oncoming cart Record an elastic collision with a cart moving at constant speed with a cart of equal mass originally at rest3 Save the video refer to 34 pp19 for instructions4 Open video point to begin analysis of the motion 341 pp 19-205 Construct a distance vs time graph and a velocity vs time graph for A the cart in motion before the collision B the carts in motion after the collision Three sets of the distance and velocity graphs may6 On the velocity vs time graph find the average velocity click the F button on the top right-hand side of the graph and select average Print both graphs - distance velocity7 Repeat this procedure from the step number two for the entire four scenarios8 The
