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:
Gravity acts on a body under free fall.
The correct answer is: Always
Here the correct option will be 'c' i.e; always. This is because the object is only experiencing gravity ignoring the air resistance and this is during its entire journey, whether it is going upwards or coming downwards. It does not depend on the direction of the moving body.
