Simple Machines

Front

What are the six types of simple machines?

Back

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

Front

What is a lever and how does it work?

Back

A lever is a rigid bar that rotates around a fixed point called the fulcrum. It is used to lift or move loads with less effort.

Define a pulley and its function.

Back

A pulley is a simple machine consisting of a wheel on an axle or shaft that is designed to support movement and change the direction of force.

What is the purpose of a fulcrum in a lever system?

Back

The fulcrum is the pivot point around which the lever rotates, allowing the lever to amplify force applied to one end.

Explain how an inclined plane reduces the effort needed to lift an object.

Back

An inclined plane allows an object to be raised over a distance with less force by spreading the effort over a longer distance.

What is a wedge and how is it used?

Back

A wedge is a simple machine that consists of two inclined planes joined together, used to split, cut, or lift objects.

Describe the wheel and axle and its advantages.

Back

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

What is a screw and how does it function as a simple machine?

Back

A screw is an inclined plane wrapped around a cylinder, used to hold objects together or lift materials.

Front

How does a pulley system make lifting easier?

Back

A pulley system can change the direction of the force applied, allowing for easier lifting of heavy objects.

What is mechanical advantage in the context of simple machines?

Back

Mechanical advantage is the ratio of the output force produced by a machine to the input force applied, indicating how much a machine amplifies force.
