Solution

The correct option is B speed is scalar while velocity is vector.
Speed has only magnitude and no direction. Hence, it is a scalar.
Velocity has both magnitude and direction and follows vector law of addition. Hence it is a vector.

Find the scalar and vector from the following speed, distance, current, time, velocity, pressure , work done, Momentum and acceleration

In Exercises 3.13 and 3.14, we have carefully distinguished between average speed and magnitude of average velocity. No such distinction is necessary when we consider instantaneous speed and magnitude of velocity. The instantaneous speed is always equal to the magnitude of instantaneous velocity. Why?
