6 th Grade.  Machines that are used to reduce the amount of force required to do work  EX: Lift a load  But you must apply this force over a greater.

Work and Simple Machines. Work is the use of force to move an object some distance. Work is done only when an object that is being pushed or pulled actually.

What is a simple machine? Machines are used to make the work easier or reduce the amount of force required to do work. The amount of WORK stays the same.

LEVERS:. Pulleys  A pulley is a simple machine that is made up of a single wheel and an axel.  The wheel has a groove around it so a rope or cable can.

Simple Machines Notes.

Simple Machines. Forces and Motion Force is a push or a pull. The amount of force you have to use on an object depends on its mass. Motion is a change.

A simple machine is a device that helps reduce the amount of force required to do work. Work is done when a force (effort force) is applied over a distance.

Work and Simple Machines. Work Work means to (1) apply a force to an object over a distance, and (2) the object moves in response to the force. If something.

Inclined Planes and Pulleys

Inclined Plane A flat surface that is raised. Reduces the amount of force needed to move an object up. A simple machine.

Examples of Inclined Planes: Ramp on a moving truck Escalator Stairs Handicap ramp

Shorter the ramp has less distance, but more force needed to move the object. Longer the ramp has more distance, but needs less force to move the object.

Pulleys A simple machine. A wheel with a groove in it. A rope/cable goes into the groove.

Pulleys can: Change direction of force Change amount of force Change direction & amount of force

Fixed Pulley Stays attached. Does not change the amount of force Only changes the direction of force. Easier to push down than to pull up.

Moveable Pulley The mass is attached to the pulley. The pulley moves on the rope.

Advantage: Cuts the amount of force needed to move the mass. Disadvantage: You have to pull or push the pulley up or down.
