Question

Answer the following question in brief: When we throw a ball upward, what happens to its speed while it is going up? Give reason for your 1. answer.

Answer 1

When we throw a ball upwards, its speed retards gradually.

This is because the earth produces a gravitational force which brings down everything that goes up.

So when a ball is thrown upward the gravity applies force to bring it down which decreases its speed of going up.

And at a certain point, it stops and starts falling down.
