What are the four ways energy is transferred?
1) Mechanical work 2) Electrical work 3) Heating 4) Radiation
2 of 7
Describe how energy is transferred in a kettle heating water.
The energy is transferred electrically to the internal store of the kettles heating element, which transfers energy by heating to the water's internal energy store.

What is the equation for Kinetic Energy?
Ek = 1/2 x m x v^2 (Kinetic energy(J) = 1/2 x mass (Kg) x speed^2 (m/s^2)

What is the equation for Gravitational Potential Energy?
Ep = m x g x h (GPE (J) = mass (Kg) x gravitational field strength (N/Kg) x height (m)

What is the equation for Elastic Potential Energy?
Ee = 1/2 x k x e^2 (EPE (J) = 1/2 x Spring constant (N/m) x extension^2 (m)
