1. **Definition**:
- Kinetic Energy: Energy possessed by an object due to its motion.
- Potential Energy: Energy possessed by an object due to its position or configuration.
2. **Example**:
- Kinetic Energy: A moving car has kinetic energy because it's in motion.
- Potential Energy: A stretched spring has potential energy due to its position; a ball held above the ground has gravitational potential energy.
3. **Unit**:
- Kinetic Energy: Joules (J).
- Potential Energy: Joules (J).
4. **Dimension**:
- Kinetic Energy: [M][L]^2[T]^-2 (Mass × Length^2 × Time^-2)
- Potential Energy: [M][L]^2[T]^-2 (Mass × Length^2 × Time^-2)
Both kinetic and potential energy have the same dimensions because they are both measures of energy, which has the dimensions [M][L]^2[T]^-2.
