Define the term ‘energy’. Write the names of different forms of energy. Establish an expression for gravitational potential energy.
Energy is the ability or capacity to do work.
Different forms of energy include:
- Kinetic Energy: Energy associated with the motion of an object.
- Potential Energy: Energy stored in an object based on its position or state.
Gravitational potential energy is the energy possessed by an object due to its position above the ground. The expression for gravitational potential energy (PE) is:
PE = m × g × h
