Chapter 2, Problem 33R

To determine

To compare: The pair velocity and momentum.

Explanation of Solution

Introduction:

Velocity can be defined as the rate of change of distance with time. It has both direction and magnitude. But momentum is the product of velocity and mass.

To figure out how far an object is positioned or how quickly it is moving; one wants a reference point from which it should be measured. Any physical calculation begins from a point of reference.

Velocity is the rate at which distance changes with time. It has direction as well as magnitude. Velocity is expressed in m/s.

Momentum is expressed in $\text{kg}\cdot \text{m/s}$ .

Conclusion:

Hence, velocity is the rate of change of distance with time and product of mass and velocity is the momentum.
