What name is given to the energy stored in bonds between molecules?
chemical potential energy
elastic potential energy
gravitational potential energy
thermal energy
What is the equation used to calculate gravitational potential energy?
gravitational potential energy = mass × gravitational field strength
gravitational potential energy = mass × (height)²
gravitational potential energy = mass/height
gravitational potential energy = mass × gravitational field strength × height
What is specific heat capacity?
the temperature change when 100J of energy is transferred to 1kg of a substance
the amount of energy required to change the state of 1kg of a substance with no change in temperature
the mass of a substance that can store 1kJ of energy with no change in temperature
the amount of energy required to raise the temperature of 1kg of a substance by 1°C

Why are some people opposed to the use of wind as an energy resource?
wind turbines take up large areas of land that could be used for farming
wind turbines are very reliable
wind is renewable
wind is a store of kinetic energy
Which pathway describes the change in the way energy is stored when a vehicle slows down?
