Do you know that there are different types of collisions? This video explores the difference between elastic and inelastic collisions. [14:25]

In this video, learn how to solve an elastic collision problem to find the final velocities using the shortcut approach. [10:19]

In this video,learn how to solve elastic collision problems the hard way. The hard way means using the conservation of momentum and conservation of kinetic energy by substituting one equation into the other and solves for the final...

This video lesson from Khan Academy covers the center of mass for student who are studying high school physics. Sal gives a conceptual understanding of what center of mass means.

In this video, David derives the expression that we can use as a shortcut to solve for finding the velocities in an elastic collision problem. [12:21]

This lesson demonstrates how bouncing objects increase impulse.
