Answer:
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.

Answer:
The speed of the ball starts decreasing. When we throw a ball upwards the Earth's gravity tries to bring it down therefore, it starts retarding.
