Question

Fig. shows a man with a parachute. Name the force which is responsible for his downward motion. Will he come down with the same speed without the parachute?

Answer 1

1. Gravity is a force that attracts a body towards the centre of the earth, or towards any other physical body having mass.
2. A few examples of gravity at work are:

1. The gases in the sun are held together by gravity.
2. Gravity is responsible for water to rest at the bottom of a glass instead of hovering over at the top of the glass.

3. Here, in this case, his downward motion is due to the force of gravity. His speed will be faster if he lands without a parachute.

4. Without a parachute, he won’t come down at the same speed because there will be less air friction.
