Newton's first law: An object at rest will stay at rest or an object in motion continues to be in motion unless acted upon by an external force."

Example #1: In this image, it shows that a golf ball has been hit. If there was no external force, the golf ball would continue to be in motion. Since there is an external force (gravity), it pulls the golf ball down towards the earth.

Example #2: in this image, the object in rest is the coin. The external force is the hand, which will pick the coin up. If there was no hand to disturb it's rest, it would stay still and not move.

Newton's second law: A force is needed to cause an object (mass) to accelerate.

Example #1: In this image, it shows that in order for the car and bike (mass) to move, there must be a force. Because of the force, the mass accelerates. More force is needed to accelerate an object with more mass.

Example #2: In this image, it shows that in order for the box to accelerate , there must be a force, which is the person pushing the box. Since the person is pushing with enough force, the box accelerates.

Newton's third law: Every action has an equal and opposite reaction.

Example #1: As shown in this image of a plane , there are two examples of Newton'S third law. The reason the plane can take off and increase in altitude is because air is getting pushed down because of the curvature of the wings. Without the air getting pushed down, there would be nothing to push the plane up. Another example is that the plane can move forward because of the air getting pushed back by the engines. Air enters the engines, and the the engines push the air back, allowing the plane to move forward.

Example #2: In this image of a swimmer, there is an example of Newton's third law. In order to move, the swimmer pushes the water back but as an opposite reaction, the force of the water is pushed against the swimmer.
