Explanation:
WHAT IS A FORCE?
A force is a push or a pull. Forces can make object moves or stop, speed them up or slow them down. If you push a toy car it moves, if you push it harder it moves faster. Forces can also make objects change direction or shape.
A lighter object needs less force to move than a heavier object. For example you could push a n empty box easily, but a filled box would be harder, it would need more force to move.
If you give a toy car a push what happens? It speeds up and then slows down. The reason it slows down is because of two forces, air resistance and friction.
Air resistance is air pushing on a moving object which slows it down.
Friction is the force between two objects when you rub them together.
