Two gliders collide in an elastic collision. The x-coordinate of the center of mass of the system of gliders is shown as a black dot. Play the animation. Click Show Graph. The velocities of the two objects and of the center of mass will be displayed as a function of time. Try collisions for different values of mass and initial velocity. After a while, you should be able to predict the final velocities, given any pair of initial velocities.
Inputs
Mass of Red kg
Mass of Blue kg
Initial velocity of Red m/s
Initial velocity of Blue m/s
Outputs
CM velocity m/s
X-cm m
