The car parked in a driveway has Potential Energy
- The energy possessed by an object as a result of its position in relation to other objects, internal tensions, electric charge, or other causes is known as potential energy.
- The force acting on the two objects determines the potential energy formula. The formula for gravitational force is W = m×g×h = mgh.
- The mass in kilograms is denoted by m. The acceleration owing to gravity is denoted by the letter g. The height in metres is denoted by h.
- Two types of Potential energy are mainly: Gravitational Potential energy and Elastic Potential energy.
- The energy possessed by an object as it rose to a particular height against gravity is known as gravitational potential energy.
- Elastic potential energy is the energy held in items like rubber bands, trampolines, etc. that can be compressed or stretched. The more elastic potential energy an object has, the more it can stretch.
- The units for gravitational potential energy are the same as those for kinetic energy: kg m²/s²
