As a child Newton was not very interested in school work but later on he is considered one of the most scientific minds of all time.

Newton discovered gravity while he was sitting under an apple tree. When the apple fell on his head he started to wonder what pulls the apple down.

His mother wanted him to become a farmer but he tried and he failed miserably at it. He later on went to college to study law.

The acceleration of an object as produced by a net is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

An object in rest will stay in rest and an object in motion will stay in motion unless acted upon by an unbalanced force.

For every action there is always an equal and opposite reaction.

Newton's 1st Law of Motion

Newton's 1st Law of Motion states that an object in motion will stay in motion unless acted upon by an out side force same thing if the object is at rest. In one of the videos that I watched it said that this means things are lazy. If you kicked a ball it would fly through the air forever the only reason the ball would ever stop is the air around it, a rough surface, or something like a large pole or tree hitting it. If we were in space this ball would keep moving forever unless it bumped into a planet or something. If something was at rest and you pushed on it, it would move but if you didn't push on it or ever touch it this object would stay there forever. It is so lazy it won't move itself so it would remain there forever. For this it would work the same in space.

Newton's 2nd Law of Motion

The second law is mostly about gravity and mass. Gravity is what pulls things down and keeps them on the ground. Mass is the weight of the object. For one of the experiments that we did was that gravity pulled one of the balls that hits the other ball. The bigger ball has more force because of it's mass than the smaller ball so it pushes the smaller ball farther than the smaller ball can push it.

Newton's 3rd Law of Motion

Newton's 3rd Law of Motion states that for every action there is always an equal and opposite reaction this means that if you are pushing on a wall it will push right back with equal and force so that it will stay where it is. This is also how you can sit on a chair. When you sit down your body is pushing on the chair the chair is pushing up with the same force this keeps you up if it didn't push back you would end up crushing the chair. There are plenty of different examples of this.
