Overview

In our daily lives, we often need to move heavy objects or perform tasks that require a lot of effort. Simple machines help us do these tasks more easily by reducing the amount of force needed or changing the direction of the force. A simple machine is a basic mechanical device that helps us perform

Key Concepts

A machine is a device

A machine is a device that helps us do work more easily by reducing the effort needed, changing the direction of force, or transferring force to a con

Mechanical advantage (MA) is the ratio

Mechanical advantage (MA) is the ratio of the load lifted to the effort applied. It tells us how much a machine multiplies our effort. If MA is greate

A lever is a rigid rod

A lever is a rigid rod that turns around a fixed point called the fulcrum. There are three classes of levers based on the positions of the fulcrum, lo

A pulley is a wheel

A pulley is a wheel with a groove that holds a rope. It changes the direction of the effort, making it easier to lift loads. For example, pulling down

An inclined plane is a sloping

An inclined plane is a sloping surface that allows us to move heavy objects upward with less effort. The longer and less steep the slope, the easier i
