This Mind Map on the top is all about the Newton’s 3 Laws of Motion.
The first law is an object in motion will stay in motion, and an object at rest will stay at rest unless an unbalanced force acts on it. For example, if you are driving a car, when it stops suddenly, the things on the car will fall off. That is when the unbalanced force acts. Friction is a resistance caused by any two objects in contact and it always act in the opposite direction of that force.
The second law is when an object that has an unbalanced force acting on it will accelerate in the direction of that force. Every time, Gravity pulls the mass toward the centre of the Earth. The upward normal force of the ground is pushing up against Gravity(two forces cancel out) so that means that you will not move. When you go on a slide, Gravity wins because of the angle. Gravity wins and you accelerate. In this example, There was net force always acting and making it accelerate is a combination of the normal force and the Gravity.
The third law is force always occur in equal and opposite pairs. If you push a door, it pushes right back at in with equal force. The door was on the one that moved because friction between a person’s feet and the normal force and the gravity.
