Question 4120e

Jan 14, 2017

Velocity and acceleration describe the motion of a single object.

Explanation:

Momentum (p) is measured by the product of mass and velocity.

$p = m v$

The momentum is directly proportional to an object's velocity, so its vector is along the same direction as the velocity. $p$ is also proportional to the mass of an object.

That being said, momentum is a way to describe a motion of an object by looking at the product of its mass and velocity.
