Kinetic Energy (KE)
All moving objects have kinetic energy.
From the equation we can conclude that;
- two objects with the same mass moving at different speeds, the faster object has greater kinetic energy
- two objects with the different masses moving at the same speed, the object of greater mass has greater kinetic energy
Gravitational Potential Energy (GPE)
An object held above the ground has gravitational potential energy.
From the equation we can conclude that;
- two objects with the same mass experience the same gravitational field strength, the higher the object has greater gravitational potential energy
