Review the key concepts, equations, and skills for elastic collisions, including how to predict objects' final velocities.

Block A is initially moving to the right on a horizontal frictionless surface with speed v 0. An identical block, B, is initially moving to the left with speed v 0 toward block A, as modeled …

Learn how to solve elastic collision problems using a shortcut derivation method explained in this educational video.

Learn how to handle collisions in 2 dimensions...and get better at playing billiards.

Review the key concepts and skills for inelastic collisions. Understand how to determine if a collision is elastic or inelastic.

An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision. Both momentum and kinetic energy are conserved quantities in elastic …
