2. Potential Energy

3. Potential Energy
If an object is in a state where it could do work if
released then we say that it has POTENTIAL
ENERGY
An object held above the ground has
GRAVITATIONAL potential energy (G.P.E)

4. GPE
Gravitational potential energy = mass (KG) x g x
height (m)
(g is the strength oif the
gravitational field = 10 N/kg on the
Earth).

5. 1. The potential energy of a 6 kg mass 4 m
above the ground is:
2. A 45 kg girl jumps from a 0.4 m high stool
onto the ground. How much potential energy
does she lose?
