Energy Graph Relations

Energy Graph Relations

### Formula

$$E=K+U$$

### Conditions / Special Cases

For a conservative system:

$$K=E-U$$

$$U=E-K$$

### Terminologies

- E → Total mechanical energy.

- K → Kinetic energy.

- U → Potential energy.

### Graph Interpretation

- Maximum kinetic energy occurs where potential energy is minimum.

- Turning points occur where:

$$K=0$$

$$E=U$$

### Usage

- Used in energy curve analysis.
