<span style="color: #ff0000; font-family: 'Comic Sans MS',cursive; font-size: 150%;">Work <span style="font-family: 'Comic Sans MS',cursive; font-size: 150%;"> is done when a force makes an object move.

<span style="font-family: 'Comic Sans MS',cursive; font-size: 150%;">The force that is needed to push, pull or lift and object is the <span style="color: #ff0000; font-family: 'Comic Sans MS',cursive; font-size: 150%;">effort force <span style="font-family: 'Comic Sans MS',cursive; font-size: 150%;">.

<span style="font-family: 'Comic Sans MS',cursive; font-size: 150%;">Machines make work easier.

<span style="font-family: 'Comic Sans MS',cursive; font-size: 150%;">Machines give us a <span style="color: #ff0000; font-family: 'Comic Sans MS',cursive; font-size: 150%;">mechanical advantage <span style="font-family: 'Comic Sans MS',cursive; font-size: 150%;"> by changing the amount, speed and direction of the force needed to do work.

<span style="font-family: 'Comic Sans MS',cursive; font-size: 150%;">There are <span style="color: #ff0000; font-family: 'Comic Sans MS',cursive; font-size: 150%;">6 <span style="font-family: 'Comic Sans MS',cursive; font-size: 150%;"> simple machines: lever, wheel and axle, pulley, inclinded plane, wedge and screw. Simple machines are used to make other machines.

<span style="color: #ff0000; font-family: 'Comic Sans MS',cursive; font-size: 150%;">lever <span style="font-family: 'Comic Sans MS',cursive; font-size: 150%;">- a straight rod or board that turns around a fixed point (fuclrum) and makes the makes a load easier to lift.

<span style="color: #ff0000; font-family: 'Comic Sans MS',cursive; font-size: 150%;">wheel <span style="font-family: 'Comic Sans MS',cursive; font-size: 150%;"> - a circular object that turns around a rod (axle).

<span style="color: #ff0000; font-family: 'Comic Sans MS',cursive; font-size: 150%;">axle <span style="color: #000000; font-family: 'Comic Sans MS',cursive; font-size: 150%;">﻿- the rod part of a wheel and axle.

<span style="color: #ff0000; font-family: 'Comic Sans MS',cursive; font-size: 150%;">pulley <span style="color: #000000; font-family: 'Comic Sans MS',cursive; font-size: 150%;"> - a simple machine that has a rope wrapped around a grooved wheel and makes objects easier to lift.

<span style="color: #ff0000; font-family: 'Comic Sans MS',cursive; font-size: 150%;">inclined plane <span style="color: #000000; font-family: 'Comic Sans MS',cursive; font-size: 150%;"> - a simple machine with a sloped surface like a ramp.

<span style="color: #ff0000; font-family: 'Comic Sans MS',cursive; font-size: 150%;">wedge <span style="color: #000000; font-family: 'Comic Sans MS',cursive; font-size: 150%;">- a simple machine with a thick end and a thin end; the thin end is used to lift, hold or push objects

<span style="color: #ff0000; font-family: 'Comic Sans MS',cursive; font-size: 150%;">screw <span style="color: #000000; font-family: 'Comic Sans MS',cursive; font-size: 150%;"> - a simple machine that has an inclinded plane wrapped around the core. A screw can be used to lift things or hold things together.

<span style="font-family: 'Comic Sans MS',cursive; font-size: 150%;">Simple machines make work easier and change the amount or direction of force needed to do work.

<span style="font-family: 'Comic Sans MS',cursive; font-size: 150%;">The following key ideas were learned about forces and how they affect the movement of objects:


 * 1) <span style="font-family: 'Comic Sans MS',cursive; font-size: 140%;">A <span style="color: #ff0000; font-family: 'Comic Sans MS',cursive; font-size: 140%;">force <span style="font-family: 'Comic Sans MS',cursive; font-size: 140%;">is a push or a pull that moves and object or holds it in place.
 * 2) <span style="font-family: 'Comic Sans MS',cursive; font-size: 140%;">Forces can be measured with a spring scale. The spring scale measures <span style="color: #ff0000; font-family: 'Comic Sans MS',cursive; font-size: 140%;">weight <span style="font-family: 'Comic Sans MS',cursive; font-size: 140%;"> (the force of gravity on an object).
 * 3) <span style="color: #ff0000; font-family: 'Comic Sans MS',cursive; font-size: 140%;">Friction <span style="font-family: 'Comic Sans MS',cursive; font-size: 140%;">is a force that slows or stops movement. Surface texture affects the amount of friction between objects.
 * 4) <span style="color: #ff0000; font-family: 'Comic Sans MS',cursive; font-size: 140%;">Surface texture <span style="font-family: 'Comic Sans MS',cursive; font-size: 140%;"> (the way an object feels), <span style="color: #ff0000; font-family: 'Comic Sans MS',cursive; font-size: 140%;">slope <span style="font-family: 'Comic Sans MS',cursive; font-size: 140%;"> (change in height between two points) and <span style="color: #ff0000; font-family: 'Comic Sans MS',cursive; font-size: 140%;">load <span style="font-family: 'Comic Sans MS',cursive; font-size: 140%;"> (weight of an object you are trying to move) affect the amount of force needed to make an object move.
 * 5) <span style="font-family: 'Comic Sans MS',cursive; font-size: 140%;">Forces can be combined to affect the way things move. When two forces of equal strength act in opposite directions they are <span style="color: #ff0000; font-family: 'Comic Sans MS',cursive; font-size: 140%;">balanced forces <span style="font-family: 'Comic Sans MS',cursive; font-size: 140%;"> and an object will not move. When forces on an object are balanced the object is said to be in <span style="color: #ff0000; font-family: 'Comic Sans MS',cursive; font-size: 140%;">equilibrium <span style="font-family: 'Comic Sans MS',cursive; font-size: 140%;"> and there is no change in the motion of the object. <span style="color: #ff0000; font-family: 'Comic Sans MS',cursive; font-size: 140%;">Unbalanced forces <span style="font-family: 'Comic Sans MS',cursive; font-size: 140%;">happen when one of the forces acting on an object is greater than the other forces acting in the opposite direction. Unbalanced forces allow an object to move.
