The most important thing to realize is that throughout a ball's trajectory, it will always be in any of these 4 different modes: sliding, rolling, spinning,stationary, or airborne (all of these states occur during the ball-cloth interaction, with the exception of the airborne state, which is covered later on ). The PhysicsBowl exam MUST be proctored. Additional team members could hold the meter stick steady and/or record the data. Another way to understand collisions is through Newton's 3rd Law, which tells us that "for every action, there is an equal and opposite reaction". There is a second hot-spot in the lower-right corner of the iFrame. This is the reason that after the cue ball collides with a stationary pool ball, it sometimes moves in a new direction, sometimes leading to a "scratch". In the following, use a coordinate system in which m2 is at the origin and the positive x axis goes from m2 toward m3 Enter an expression for the x component of the center of mass Enter an expression for the y component of the center Exited settings.
