Simple Machines

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 is Mechanical Advantage (MA)?

Back

Mechanical Advantage (MA) is the ratio of the output force produced by a machine to the input force applied. It indicates how much a machine multiplies force.

Front

What type of simple machine is a lever?

Back

A lever is a simple machine that consists of a rigid bar that pivots around a fixed point called the fulcrum.

Front

What is an inclined plane?

Back

An inclined plane is a flat surface that is tilted at an angle to help lift objects by reducing the amount of force needed.

Front

What is a wedge?

Back

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

Front

What is a pulley?

Back

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

Front

What is a wheel and axle?

Back

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

Front

How does a shovel function as a compound machine?

Back

A shovel functions as a compound machine because it combines a lever (the handle) and a wedge (the blade) to lift and move materials.

Front

What is the formula for calculating Mechanical Advantage?

Back

Mechanical Advantage (MA) = Output Force / Input Force.

Front

What is the purpose of using simple machines?

Back

The purpose of using simple machines is to make work easier by reducing the amount of force needed to perform tasks.
