Work done

• In I/GCSE physics, work done = force x distance
• Work done is equal to energy transferred

Power

• Power = work done / time taken
• The rate of energy transfer as it is where a lot of energy is transferred in a short period
• It is measured in watts

Gravitational Potential Energy

• It is the energy stored in an object before it falls in I/GCSE physics
• Gravitational potential energy = mass x g x height

Kinetic Energy

• Kinetic energy = ½ x mass x speed2

Conservation of energy

• Kinetic energy gained = gravitational potential energy lost
