Title: Understanding Energy Transformations in a Bouncing Ball

---

**Concept Overview:**

When you hold a rubber ball at eye level and drop it, the ball will bounce back but not reach its original height. This phenomenon involves energy transformations, which are crucial to understanding why the ball behaves this way. Let's explore the energy conversions that occur during this process.

**Energy Transformation Process:**

1. **Initial Drop:**

   - As the ball falls, its potential energy (due to its height) is converted into kinetic energy (energy of motion).

2. **Impact with the Floor:**

   - When the ball strikes the floor, its **kinetic energy is converted to elastic potential energy** as it is flattened. This conversion allows the ball to store energy temporarily.

3. **Rebound:**

   - The stored elastic potential energy is then converted back into kinetic energy, allowing the ball to bounce back up.

4. **Ascent After the Bounce:**

   - On its way up after bouncing, the ball's **kinetic energy is converted back into potential energy** until it reaches its highest point and stops momentarily.

**Why the Ball Does Not Reach Its Original Height:**

- During each bounce, some of the ball’s original energy is lost, primarily as heat due to internal friction and air resistance. This energy loss means the ball does not have the same kinetic or potential energy to reach its initial height on subsequent bounces.
