What is a simple machine?

Back

A simple machine is a device that makes work easier by allowing us to apply force in a more efficient way.

Front

What are the six types of simple machines?

Back

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

Front

How does an inclined plane make work easier?

Back

An inclined plane reduces the amount of effort needed to lift an object by allowing it to be moved over a longer distance at a lower height.

Front

What is the trade-off when using a simple machine?

Back

The trade-off is that while the input force is decreased, the distance over which the force is applied is increased.

Front

What 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 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.

Front

What is a pulley?

Back

A pulley is a simple machine that uses a wheel and a rope to lift or lower objects.

Front

What is a screw?

Back

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

Front

What is a wedge?

Back

A wedge is a simple machine that is used to split or cut objects apart, consisting of two inclined planes.

Front

What does it mean to change the direction of a force?

Back

Changing the direction of a force means using a machine to redirect the force applied, making it easier to move an object.
