Collisions can be elastic or inelastic. Learn about what's conserved and not conserved during elastic and inelastic collisions.

There's different ways you could characterize this collision, but one thing that physicists are almost always interested in is whether this collision is going to be elastic or inelastic.

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 …

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

Collisions can be elastic or inelastic. Learn about what's conserved and not conserved during elastic and inelastic collisions.

If the kinetic energy is the same, then the collision is elastic. If the kinetic energy changes, then the collision is inelastic regardless of whether the objects stick together or not.

Ram explains what it means for a collision to be elastic or inelastic. Created by Ram Prakash.

Learn about elastic and inelastic collisions, their differences, and applications in the context of force, motion, and energy.

What's the difference between an elastic and an inelastic collision? What we mean by an elastic collision is that the total kinetic energy of that system is conserved during the collision.

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.
