Changes in energy (AQA GCSE Physics): Flashcards

Energy that moving objects have

$E_k = \frac{1}{2}mv^2$

Becomes zero

Doubles kinetic energy

Increases by four times

Energy gained when lifted above ground

$E_p = mgh$

10 N/kg

Energy stored in stretched/compressed springs

$E_e = \frac{1}{2}ke^2$

Joules (J)

Forgetting to square the speed

Convert cm to m (divide by 100)
