Q: A perfectly inelastic collision reduces internal kinetic energy to the minimum it can have while still conserving what?


Read this paragraph and choose the correct option from the provided answers:

rest after sticking together, conserving momentum. But the internal kinetic energy is zero after the collision. A collision in which the objects stick together is sometimes called a perfectly inelastic collision because it reduces internal kinetic energy more than does any other type of inelastic collision. In fact, such a collision reduces internal kinetic energy to the minimum it can have while still conserving momentum. Perfectly Inelastic Collision A collision in which the objects stick together is sometimes called “perfectly inelastic.

 Choices:

- heat

- energy

- elements

- momentum


A:
momentum
