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
