Elastic and Inelastic collisions
The truth about …Slide2
The only way to tell …
… whether a collision is elastic or inelastic is to find out whether
kinetic energy
is conserved or not.
You have to calculate the kinetic energy before and after the collision.
Note that
energy
is always conserved but kinetic energy is turned into heat and/or sound in an inelastic collision.
