POWER, FORCE, ENERGY ANS SIMPLE MACHINE

is a device that makes work easier by changing the size or direction of a force.

The energy stored in the bonds between atoms in molecules is called

Newton's First Law of Motion is also known as the law of

1. Motion states that for every action, there is an equal and opposite reaction force. 

It always works in the direction opposite from the direction the object is moving, or trying to move.

1. Straight, slanted surface

Makes work easier because it is easier to move something to a higher or lower place

 stair steps, sloping road and ramp

1. Wider or thicker at one end than at the other

• Makes work easier because when moved, a wedge cuts, splits, or pries apart objects (including air and water)

• Example : axe and knife 

1. nclined plane wrapped around a cylinder with a wedge at the tip, with thread

        Makes work easier because it applies lots of force with little effort

Example: drill bits, jar lid, cork screw

1. Made up of a bar that pivots at a fixed point called a fulcrum

-Force applied to a lever is called the effort
