Flashcard on Simple Machines

Front

What is a simple machine?

Back

A simple machine is a device that changes the direction or magnitude of a force, allowing work to be done with less effort.

Front

What are the six types of simple machines?

Back

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

Front

What is a lever?

Back

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

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

What is the fulcrum in a lever system?

Back

The fulcrum is the pivot point around which the lever rotates.

Front

How does an inclined plane work?

Back

An inclined plane allows a load to be raised by applying a smaller force over a longer distance.

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 of loads.

Front

What is a screw?

Back

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

Front

What is the input force in a wheel and axle system?

Back

The input force is applied at the rim of the wheel.

Front

What are the two sides of a pulley called?

Back

The two sides of a pulley are called the input arm and output arm.
