A 2-kg block rests on a wall that is 3 m tall. What is the gravitational potential energy of the block? The force of gravity on Earth (
g. is equal to 9.8 m/s2.

Respuesta :

PE= weight x height. (remember weight is the force of gravity acting on objects...NOT the same as mass)

PE=3*2*9.8
PE=6*9.8
PE=58.8 J (for joules which is the unit for both Kinetic and potential energy)

Hope this helps :D
