K.E. an GPE

Question 1

Equation for kinetic energy

Answer 1

kinetic energy = ½ x mass x (speed)2

K.E. = ½ x m x v2

[joules] = [kilograms] x [m/s]2

Question 2

Equation for gravitational potential energy

Answer 2

gravitational energy = mass x gravitational field strength x height

G.P.E. = m x g x h

[joules] = [kilograms] x [N/kg] x [m]
