Simple machines

What is a simple machine?

A simple machine is a devices or tools that have few or no moving parts

Name the six types of simple machines.

Lever, Inclined Plane, Wheel and Axle, Pulley, Screw, and Wedge.

What is a lever?

A lever is a rigid bar that pivots around a fixed point known as the fulcrum.

What is an inclined plane?

An inclined plane is a flat surface that is tilted at an angle to help raise or lower objects.

What is a wheel and axle?

A wheel and axle consist of a large wheel attached to a smaller axle, allowing objects to move more easily.

What is a pulley?

A pulley is a wheel with a groove that holds a rope or cable, enabling the lifting of heavy objects.

What is a screw?

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

What is a wedge?

A wedge is a simple machine that converts force applied to its blunt end into forces perpendicular to its inclined surfaces.

How do simple machines make work easier?

Simple machines reduce the amount of force needed to perform work and can change the direction of the force.

Give an example of a lever in everyday life.

A seesaw or a pair of scissors are examples of levers used in everyday life.
