In an inelastic collision, the total final kinetic energy of the system is less than the total initial kinetic energy of the system because some of the energy is dissipated as other forms of …

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

Elastic collisions and conservation of momentum Learn What is conservation of momentum?

An inelastic collision is a collision in which there is a loss of kinetic energy. While momentum of the system is conserved in an inelastic collision, kinetic energy is not.

For a collision where objects will be moving in 2 dimensions (e.g. x and y), the momentum will be conserved in each direction independently (as long as there's no external impulse in that …

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.

While masses could bounce during an inelastic collision, if they stick together, the collision is typically called a perfectly inelastic collision, since in this collision you'll transform the most …

In this video, David solves an example elastic collision problem to find the final velocities using the easier/shortcut approach.
