The Law of Conservation of Energy states:

• Energy can created or destroyed but not transformed

• Energy cannot be created or destroyed, it can only transformed

• Energy can't be created, destroyed or transformed

• Energy cannot be created or destroyed.

A student is holding a stone at a certain height. The stone has 50 joules of potential energy and 0 joules of kinetic energy. The stone is released from that height. How much energy does the stone have right before it hits the ground?

• The stone will have no energy.

• The stone will have about 50 joules of kinetic energy and 0 joules of potential energy.

• The stone will have about 50 joules of potential energy and 0 joules of kinetic energy.

• The stone will have about 25 joules each of kinetic and potential energy.
