Simple Machines

Front

What is a simple machine?

Back

A simple machine is a mechanical device that changes the direction or magnitude of a force, making work easier.

Front

What are the six types of simple machines?

Back

The six types of simple machines are lever, inclined plane, wedge, screw, pulley, and wheel and axle.

Front

What is the function of a lever?

Back

A lever is used to amplify force, allowing a small input force to lift a larger load.

Front

What is a fulcrum in relation to a lever?

Back

A fulcrum is the pivot point around which a lever rotates.

Front

What is an inclined plane?

Back

An inclined plane is a flat surface that is tilted at an angle to help raise or lower objects.

Front

How does a wedge function as a simple machine?

Back

A wedge is a device that tapers to a sharp edge, used to split or cut objects apart.

Front

What is a wheel and axle?

Back

A wheel and axle is a simple machine consisting of a larger wheel attached to a smaller axle, allowing for easier movement.

Front

What is the purpose of a pulley?

Back

A pulley is used to change the direction of a force, making it easier to lift heavy objects.

Front

How does a screw function as a simple machine?

Back

A screw converts rotational force into linear motion, allowing it to hold objects together or lift materials.

Front

What is the mechanical advantage of using simple machines?

Back

The mechanical advantage is the factor by which a machine multiplies the force applied to it, making work easier.
