Question

A body is thrown vertically upwards. It’s acceleration ___ as it reaches the maximum height.

  1. Is non-uniform
  2. Decreases uniformly
  3. Increases uniformly
  4. Remains the same

hintHint:

The total energy for the motion of the body will remain constant.

The correct answer is: Remains the same


    A body is thrown vertically upwards. Its acceleration Remains the same as it reaches the maximum height.
    Even when the body will start to fall down the acceleration will also be the same in a different directions.

    An object starts from rest. It means that _____.

    Rest implies that the body was stationary with respect to the ground. Any body which doesn't move has zero velocity, since it doesn't covers any distance. Thus, any body starting from rest has initial velocity= zero.
