When the car stops fast you fall forward into the seatbelt and the seatbelt pushes you back, which law is this.

Newtons 3rd law states that every action has an equal and opposite reaction, like how the seatbelt pushes back when you pull forward.

How does water move through plants?

Adhesion moves water up the walls while cohesion sticks the water together.

A soccer ball stays in the same place until it gets kicked, which law is this?

Newtons 1st law, also known as the law of inertia, says that an object in motion will stay in motion and an object at rest will stay at rest unless an outside force acts on it.
