Question
Explain how an object could have zero average velocity but non-zero average speed?
✓
Answer
Average velocity, $\text{v}_{\text{av}}=\frac{\text{Net displacement}}{\text{Total time taken}}$ and average speed, $\text{s}_{\text{av}}=\frac{\text{Total distanve travelled}}{\text{Total time taken}}$ If an object moves along a straight line starting from origin and then returns back to origin. Average velocity = 0 And Average Speed $=\frac{2\text{s}}{\text{t}}$
