potential energy
Potential energy is the stored energy in an object due to its position, arrangement, or state, such as height, stress, or electric charge
kinetic energy
Kinetic energy is the energy an object possesses due to its motion
elastic energy
Elastic energy is the mechanical potential energy stored in an elastic object when it is deformed, such as being stretched, compressed, or bent
chemical potential energy
Chemical potential energy is the energy stored within the chemical bonds of a substance
gravitational potential energy
Gravitational potential energy (GPE) is the energy an object has due to its position in a gravitational field
mechanical energy
Mechanical energy is the total energy of an object due to its motion (kinetic energy) and its position (potential energy)
