If a body starts from a point, and returns back to the same point, then its
Correct answer: A. Average velocity is zero but not average speed
- A. Average velocity is zero but not average speed
- B. Average speed is zero but not average velocity
- C. Both average velocity and average speed are not zero
- D. Both average speed and average velocity are zero
Explanation
Average speed is calculated as the total distance traveled divided by the time taken, while average velocity is calculated as the total displacement divided by the time taken. In this scenario, the body returns to its starting point, making the displacement zero. Therefore, the average velocity is zero. However, the average speed is not zero because the body covers a certain distance. Options B, C, and D are incorrect because they either misunderstand the definitions or misapply the concepts of average speed and average velocity.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
