Kinetic and Potential Energy Most of us think of energy as the power
... Most of us think of energy as the power our bodies have to move or do work. We have a lot of energy when we are rested or excited, and less energy when we are tired or bored. But that is only one kind of energy. Energy is working all around us. It powers cars and gives us light. Energy keeps us warm ...

... SPEED is how rapidly an object moves or changes its position. It is calculated by dividing how far an object moves by the time taken to move. Speed = (distance moved) / (time taken moving) Example. If a runner covers 400m in 50 s, the average speed is 400m / 50 s = 8 m/s ACCELERATION is how rapidly ...
