Science 6 (Simple Machine)

It is a device that helps make man’s work easier. It helps us use our muscle's power to do work better. It provides force and controls the direction of force but it cannot create energy.

• Simple Lever

• Simple Machine

• Simple Things

• Simple Equipment

It comes from the force that is applied to the machine, or the effort force

• Work input

• Work output

The machine does work, too. It exerts a force, called an output force, over some distance.

• Work Input

• Work Output

It is a rigid bar, straight or curved, that is free to turn about a fixed point called the fulcrum

• Inclined Plane

• Wheel and axle

• Lever

• Pulley

A class of lever where the fulcrum is between effort and resistance

• First class

• Second class

• Third class

• Fourth class

It is a machine that has a large wheel connected to a smaller wheel or shaft called an axle

• Screw

• Wedge

• Pulley

• Wheel and axle

It is a wheel that turns around an axle. Usually, there is a groove in the rim of the pulley so that the rope around the pulley will not slip off.

• Wheel and axle

• Lever

• Inclined plane

It is a surface that raise at one end. It is a simple machine that gives us a gain in force.
