Force and movement
We use push and pull every day. Push and pull are forces. A force can make things move. If you push a light toy car, it moves quickly. If you push a heavy box, it is difficult to move.
The size of force changes the speed of things. A big push makes things go fast. A small push makes things go slowly. Some animals move slowly, like tortoises. Planes move fastest. They can fly very high in the sky.
Remember: light things are easier to move than heavy things.
