Question 1 Easy

Two gliders collide on a level air track with negligible friction and move apart afterward. The total kinetic energy of the two-glider system is 0.60 J just before the collision and 0.45 J just after.

Which of the following correctly describes the collision?
AElastic, because the two gliders moved apart after the collision.
BElastic, because the total momentum of the two-glider system remained constant.
CPerfectly inelastic, because the total kinetic energy of the two-glider system decreased.
DInelastic, because the total kinetic energy of the two-glider system decreased.

Topic 4.4: Elastic and Inelastic Collisions

Learning Objective: 4.4.A

Describe whether an interaction between objects is elastic or inelastic.

Essential Knowledge: 4.4.A.1

An elastic collision between objects is one in which the initial kinetic energy of the system is equal to the final kinetic energy of the system.

Essential Knowledge: 4.4.A.2

In an elastic collision, the final kinetic energies of each of the objects within the system may be different from their initial kinetic energies.

Essential Knowledge: 4.4.A.3

An inelastic collision between objects is one in which the total kinetic energy of the system decreases.

Essential Knowledge: 4.4.A.4

In an inelastic collision, some of the initial kinetic energy is not restored to kinetic energy but is transformed by nonconservative forces into other forms of energy.

Essential Knowledge: 4.4.A.5

In a perfectly inelastic collision, the objects stick together and move with the same velocity after the collision.
