Why does a tunnis ball bounce heigher on a hill than on plains?

Explanation

To understand why a tennis ball bounces higher on a hill than on flat plains, we can break down the explanation into several steps:

### Step 1: Understanding Gravitational Acceleration
The gravitational acceleration (g) at the surface of the Earth is defined by the formula:
\[ g = \frac{GM}{r^2} \]
where \( G \) is the gravitational constant, \( M \) is the mass of the Earth, and \( r \) is the radius of the Earth.

### Step 2: Effect of Height on Gravitational Acceleration
