You can calculate kinetic energy by using the equation: KE = _____.
m (kg) x 9.8 m/s2 x h (m)
1/2 m (kg) x v2 (m2/s2)
w (m) x h (m)
9.8 m/s2 x 1/2 m (kg)
You can calculate gravitational potential energy by using the equation: GPE (J) =
1/2 m (kg) x 1/2h (m)
h (m) x 9.8 m/s2
m (kg) x 9.8 m/s2 x h (m)
1/2 h (m) x w (m)
