Is it is possible that a body is in rest but it has an acceleration |
| Answer» It is possible that a body is in rest but it has an acceleration ,we can show it by following examples:-1. When you through a ball upside and when it reaches the top it pauses for a moment. At this moment, the velocity is zero but the ball still has acceleration and that acceleration is due to acceleration due to gravity. Thus at the peak, the velocity is zero but the object is still accelerating.2. Second example can be discussed in the case of pendulum. When a pendulum moves, and when it reaches the extreme positions its velocity is zero but its still accelerating due to gravity. | |
