To determine

To Compare: The pair speed and velocity.

Expert Solution & Answer
Check Mark

Answer to Problem 31R

The speed has only magnitude but doesn’t have direction. But velocity has both directions as well as magnitude.

Explanation of Solution

Introduction:

Speed is the rate at which an object covers a distance. Velocity is the rate of change of position of an object with respect to time.

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 is begun from a point of reference. Measurement is an object's state with respect to some other related parameter.

Speed is the measure of distance travelled in a given time by an object, independent of direction of motion. It has magnitude only but not direction.

Velocity is the rate at which distance changes with time. It has direction as well as magnitude.

Conclusion:

Hence, the speed has only magnitude but doesn’t have direction. But velocity has both direction as well as magnitude.
