Give an example of an object with lots of stored gravitational potential energy.

'You do' task - Describe the energy transfers taking place in each of these examples:

1

A car speeding up (remember, fuel contains an energy store.

1

A car slowing down (hint, the breaks get hotter).

1

Bringing water to the boil in a kettle.

Watch the video below and then apply your understanding of energy transfers to the Independant writing task
