Energy is a type of force that can cause things to happen or move. It is all around us and can take many different forms. Some examples of energy include light, heat, and sound.

One important thing to know about energy is that it cannot be created or destroyed. This means that energy always exists and can change forms, but it cannot be completely destroyed.

For example, when you hit a cue ball in a game of pool, you are transferring energy to the ball. The ball then hits the other ball, transferring some of its energy to that ball. The energy that was transferred from the cue ball is not destroyed, but it is now being used by the other ball to move.

Another example of energy being transferred is a Newton’s Cradle. This is a toy that consists of several metal balls connected by strings. When you lift one of the balls and let it go, it hits the other balls and causes them to move. The energy that was transferred from the first ball to the others is not destroyed, but it is now being used to make the other balls move.

In summary, energy is a type of force that can cause things to happen or move. It cannot be created or destroyed, but it can be transferred from one object to another. Examples of this include a cue ball hitting another ball in pool and a Newton’s Cradle transferring energy from one ball to another.
