Question

Give an example of a body possessing zero velocity and still accelerate.

Answer 1

1) See an example is If u throw the ball downward from a building it will have zero velocity but due to presence of gravity it will face the acceleration due to gravity which is 9.8 m/sec.
2) Consider an object moving in the forward direction. Suddenly a force acts on it and tries to accelerate the object in the backward direction. When you observe the object, you will find that the object will continue to move forward for some time and then stops momentarily. Then the object will start to move in the backward direction.When the object stops for a moment, its velocity at that instant is zero, therefore no motion in either forward or backward direction. However the acceleration is still acting on it. At that instant, the magnitude of velocity in the backward direction is equal to the velocity in the forward direction, but as the acceleration continues to act on it, the velocity in the backward direction increases in magnitude over time, and the object finally starts moving in the backward direction.
