why tennis ball bounces higher on hills than in plains??

Expert Answer:

The acceleration due to gravity varies with height as g' = (1-2h/R) where R is the radius of the Earth and h is the height.As the formula indicates g decreases as height increasesSo on the hills the acceleration due to gravity is lesser and the ball bounces higher due to lesser force of gravitation.
