Newton's 3 Laws

      

                      
                              In the late 1600's there was a man who tried to help us understand motion his name was Isaac Newton. He figured out things other people didn't even realize was there. He had three laws of motion, the first one was when an object is at rest it stays at rest and if an object is in motion it stays in motion unless an unbalanced force is acted upon it. The second law is F=m x a or Force=mass x acceleration. And the third law is if there is an action force there will be an equal reaction force.

Newton's First Law

                   NEWTONS FIRST LAW OF MOTION describes why objects continue moving or staying still unless an unbalanced force is acted upon it. An example of his first law is a hand stopping a ball after going down a ramp.

 

A ball that is rolling down a ramp  is moving, but an unbalanced force which is the hand stops the ball which is an example of Newton's first law because an object is moving but an unbalanced force is acted upon it making it stop.

 

Newton's Second Law

NEWTONS SECOND LAW OF MOTION is F= m x a or Force= mass x acceleration. In other words if there is more mass then there will be more force needed also the more the acceleration the more the force. An example of Newton's second law is someone trying to push a car.

If the mouse is pushing a car that is 907kg at a rate of 1m/s then the force will be 907N.

Newton's Third Law

                    NEWTONS THIRD LAW OF MOTION is if there is an action then there would be an equal reaction force. In other words if something moves there will always be at least one more thing moving. An example of his third law would be a bird flapping its wings.                                                                           

The bird is flapping its wings down while the air molecules are pushing back up and that is why when the bird flaps its wings it goes up.
