12 cards from this deck
Kinetic, gravitational potential, elastic potential
Energy stored in moving objects
Ek=12mv2E_k = \frac{1}{2}mv^2Ek=21mv2
Square it (v×vv \times vv×v)
Doubles the kinetic energy (directly proportional)
Increases it 4 times (proportional to v2v^2v2)
Energy gained when object raised above ground
Ep=mghE_p = mghEp=mgh
10 N/kg (gravitational field strength)
Energy stored in a stretched spring
Ee=12ke2E_e = \frac{1}{2}ke^2Ee=21ke2
Joules (J)
