FORCE AND MOTION/ Newtons LAWS
LAWS OF MOTIONS AND SIMPLE Machines.
Introduction
In class we learned about newtons laws of motion and simple machines .one example of a simple Machine is a lever you can use a lever to get a screw out of a planc of wood with the back of a hammer . And the next things are Newtons laws are all about how gravity works, and these are some of the things of what we learned in class.
A simple Machines levers
A simple machines is a meshing that is well simpe like a lever for example a lever can help get a screw out of a peace of wood with a back of a hammer to get the screw out of the planc of wood.
Simple meshin a pulley

Newtons laws 1-3
Newtons 1 law of motion is an object in motion will stay in motion endless acted a poun by an out side fours. Newtons 2 law of motion stats that acrlation mass and net force are all related. Newtons 3 law states that to every action thare is a equal or opposite reaction.
