Newtons Laws Accorinding to; Jordan Brooks

Sir Issac Newton We use his laws everyday, but who was Sir Issac Newton? Sir Issac Newton was born in 1647, he was a famous physicist. Folklore says that one day as Newton was sitting under an apple tree, an apple fell on him and Newton asked, why did the apple fall? And that is the starting point of Newton's studies on motion. Through Newtons studies we now have Newtons laws that explain why phenomenon, like apples falling, happen.

An object that is moving will continue to move until another force changes its motion. An object at rest will continue to be at rest until a force causes it to change its motion.

Newton's First Law:

Newton's Second Law:

The acceleration of a body is equal to the action onto the body and resisted by the body's mass.

In order for a body to move, a force must overcome the mass of the body. Here in the video it is easier to lift the small weight, but it becomes harder to exert enough force to overcome the mass of the heavier weight.

In this video the actions produced from the two bodies meeting are the head acts upon the ball, the ball acts upon the head equally.

Newton's Third Law:

The actions produced from two bodies meeting are equal and or opposite to each.

Because the plate is carrying a ball, when the the plate stops moving, the ball will continue to move becuase there is nothing to stop it from moving, unlike the plate.

In this pictue the actions produced from two bodies are equal and so niether body moves.

Let's say in this picture the object being held is about 9 kg or 20 lbs and to lift it I would need about 18 N of force, then the acceleration of the object is 9 m/s2

Why did the apple fall?

The ball stays at rest, until a force (the mysteriosu finger) moves it.
