Sir Isaac Newton: Sir Isaac Newton was born on December 25,1643 and lived for 85 years. He was raised by his grandmother ,and when he is older he went to Trinity Collage in Cembridge

Direction- discribes motion using north, south, east, and west. speed-mesurment of disdence over time. __Distanc____e__ time velocity-mesures disdance over time but includs direction.

Position is the location of an object. You can describe the motion by describing the original position and the ending position. You could describe a soccer ball. It could be kicked 20 meters east from the sideline. The ball that is moving 20 meters in 2 seconds is moving with a speed of 10 meters per second.

Forces Change Motion Force - a push or a pull of an object. Force cause objects to move or stop moving.The motion in the object depends on all the forces acting on it. lift - created by force and pressure. drag - a force that goes in the opposite direction. thrust - force that moves an object forward.

energy and Machines Energy is the capability to do work. All forces require energy. Machine-something that can replace human effort. Gravity- force that pulls an object to earth.

Forms of energy one type of energy can turn into another. Light bulb energy can change into heat energy.
