This law explains why when you kick a soccer ball it goes flying and you feel the force on your foot in the opposite direction.

 Newton's Third law of motion

What is Newton's First Law of Motion?

If an object is at rest it will stay at rest, if an object is in motion it will stay in motion until acted upon by an unbalanced force.

200

A force that slows down objects when they rub against each other

 friction

A car hits a wall with a force of 200 Newtons. Why does the car get damaged and not just the wall?

The wall is pushing back with a force of 200 newtons
