What does the Law of Conservation of Mass explain?

• Energy can be made, but only from something the same mass.

• Energy can move from one object to another, or change from one form to another.

• Energy can move from one object to another, but it loses about 1/2 of its energy when it moves.

• Energy can be destroyed when it is heated.

A train and a car are moving at the same speed. Explain why they do not have the same kinetic energy.

• A moving object with more mass has more kinetic energy, so the train has more kinetic energy because its mass is bigger.

• A moving object with less mass has more kinetic energy, so the car has more kinetic energy because its mass is smaller.
