Consider a situation where you exert a force F on a crate of mass m, moving it at a speed v a distance d across a floor in a time interval t.
-The quantity mv is
A)the kinetic energy of the crate.
B)the potential energy of the crate.
C)the linear momentum of the crate.
D)the work you do on the crate.
E)the power you supply to the crate.

Question

Quizplus · Accepted Answer

The quantity mv is the linear momentum of the crate. It is defined as the product of an object's mass and its velocity. Kinetic energy is given by 1/2 mv^2, potential energy depends on the position of the crate in a gravitational or electric field, work is defined as force multiplied by displacement, and power is defined as the rate at which work is done. Therefore, none of the other choices is correct.
