Simple Machines Flashcard review

Front

What is a simple machine?

Back

A simple machine is a device that changes the direction or magnitude of a force, making work easier. Examples include levers, pulleys, and inclined planes.

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 an inclined plane?

Back

An inclined plane is a flat surface that is tilted at an angle to help raise or lower objects with less effort. Example: a ramp.

Front

What is a lever?

Back

A lever is a rigid bar that pivots around a fixed point called the fulcrum, used to lift or move loads.

Front

What is a wedge?

Back

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

Front

What is a screw?

Back

A screw is a simple machine that converts rotational motion into linear motion, often used to hold objects together.

Front

What is a pulley?

Back

A pulley is a simple machine that consists of a wheel on an axle or shaft, used to lift or lower loads with the help of a rope.

Front

What is the function of a wheel and axle?

Back

A wheel and axle is a simple machine that consists of a larger wheel attached to a smaller axle, used to reduce friction and make movement easier.

Front

How does a lever work?

Back

A lever works by balancing the load and effort on either side of the fulcrum, allowing a smaller effort to lift a larger load.

Front

What is an example of a lever in everyday life?

Back

An example of a lever is a seesaw, where one side goes up as the other side goes down.
