Question
A ball that is thrown up travels a certain distance upwards and falls back to the ground. The gravitational pull acts on it ______.
- Only during its upward motion
- Only during its downward motion
- Always
- Only when it hits the ground
Hint:
Earth possesses gravity.
The correct answer is: Always
Here the correct option will be 'c' i.e; always. As gravitational force always acts on an object whether it is moving or at rest. It always acts on the object in the downward direction as the earth pulls it towards itself due to a special property known as gravity. Here the ball is under free fall so ignoring the air resistance only gravitational force is acting on it.
