Question

two properties of inelastic collisions​

Answer 1

Explanation:

If objects stick together, then a collision is perfectly inelastic. ... If the kinetic energy changes, then the collision is inelastic regardless of whether the objects stick together or not. In either case, for collisions with no external forces, momentum is conserved.

Answer 2

Answer:

 objects stick together, then a collision is perfectly inelastic. When objects don’t stick together, we can figure out the type of collision by finding the initial kinetic energy and comparing it with the final kinetic energy. 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. In either case, for collisions with no external forces, momentum is conserved.
