Potential energy changes into kinetic energy when it is put to use. True/False.

Answer

To determine whether the statement "Potential energy changes into kinetic energy when it is put to use" is true or false, we can analyze the concepts of potential energy and kinetic energy step by step.

### Step-by-Step Solution:

1. **Understanding Potential Energy**:
- Potential energy is the energy stored in an object due to its position or state. For example, an object held at a height has gravitational potential energy because of its elevated position.

2. **Understanding Kinetic Energy**:
- Kinetic energy is the energy of an object due to its motion. The faster an object moves, the more kinetic energy it possesses.

3. **Energy Transformation**:
- When an object is in a position where it has potential energy (like being held at a height), and it is allowed to move (for example, it is dropped), this potential energy can be transformed into kinetic energy.

4. **Example of Energy Conversion**:
- Consider a ball held at a certain height. While it is held still, it has potential energy. When the ball is released, it falls due to gravity, and as it falls, its potential energy decreases while its kinetic energy increases. At the moment just before it hits the ground, all the potential energy has been converted into kinetic energy.

5. **Conclusion**:
- Therefore, it is correct to say that potential energy changes into kinetic energy when it is put to use, such as when an object falls or moves. Hence, the statement is **True**.

### Final Answer:
**True**
