Which statement best describes the law of conservation of energy

Energy is not created or destroyed, it only transforms.

Explanation:

The law of conservation of energy tells us that the energy in a system must be conserved, that is, it can be transformed or exchanged between systems but not disappear or be created from nothing.

There are many types of energy such as potential energy, kinetic energy, heat, work, gravitational energy, electrical energy, etc.

An example of how energy is transformed is when we have a ball raised a certain height from the floor, it has potential energy due to its position, and when released that potential energy becomes kinetic energy that is the energy of movement.

Another exaple is a cup of coffee that loses energy by giving heat to its surroundings.

In summary, the statement is Energy is not created or destroyed, it only transforms.
