Question

Select True or False to each of the following statements about collisions. In order to receive credit for this question you must answer ALL statements correctly.
True False  In a perfectly inelastic collision, kinetic energy is conserved.
True False  If two objects undergo a perfectly elastic collision, they stick together after the collision.
True False  In an elastic collision, total momentum is not conserved.
True False  In a perfectly inelastic collision, total energy is not conserved.
True False  In an elastic collision, kinetic energy is conserved.

Explanation / Answer

(1) in perfectly in elastic collision, kinetic energy do not remain conserved

So it is False

(2) In perfectly elastic collision object do not stick together

So it is False

(3) Momentum remain conserved in each collision

So it is False

(4) this is True total energy do not remain conserve in perfectly inelastic collision

(5) This is True
