| (i) Distance is the magnitude of displacement in all cases. |
| (ii) When a body moves with uniform speed, then the average speed is same as instantaneous speed. |
| (iii) Average speed is greater than the average velocity if a body is moving in a straight line without reversing its direction. |
| (iv) When a body moves with constant velocity, the average velocity is zero. |

Correct Answer: D
Solution :
| (i) F; Distance is equal to the magnitude of displacement only when a body moves in a straight line without reversing its direction. |
| (ii) T |
| (iii) F; Average speed is equal to average velocity when a body moves in a straight line without reversing its direction. In all other cases, Average speed > |Average Velocity| |
| (iv) F |
