Answer 2

$\red{\mid{\underline{\overline{\mathbf{Answer}}}\mid}}$

When we throw a ball upwards, the speed of the ball gradually decreases. It is so because the gravitational force of the Earth attracts the ball towards it centre, resulting in the decreasing of the balls speed and after sometime it stops mid air and comes back to the Earth.
