What do you know about the law of conservation of energy? Check all the statements that are true according to this law.

The total amount of mass in a system remains constant regardless of the changes that take place in that system.
Energy is neither created or destroyed; it only changes form.
Half-way down the ramp, PE = 50J and KE = 50J.
In this energy pyramid, all the energy from level is transferred to the next level.
In a closed system, i. e., a system that isolated from its surroundings, the total energy of the system is conserved.
