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. Examples include levers, pulleys, and inclined planes.

What is an inclined plane?

Back

An inclined plane is a flat surface that is tilted at an angle to help raise or lower objects. It reduces the amount of force needed to lift an object.

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. It is used to lift or move loads.

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 wedge?

Back

A wedge is a simple machine that is used to split or cut objects. It has a thick end and a thin edge, allowing it to apply force to an object.

Front

What is a screw?

Back

A screw is a simple machine that consists of a cylindrical shaft with a helical ridge (thread) wrapped around it. It converts rotational force into linear motion.

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. When the wheel turns, the axle turns as well, making it easier to move heavy objects.

How does a screw make work easier?

Back

A screw makes work easier by converting rotational motion into linear motion, allowing us to hold objects together or lift them with less effort.

Front

What is the function of a wedge in everyday tasks?

Back

A wedge is used to separate or cut materials, such as chopping wood or keeping a door open.

Can you give an example of a lever in real life?

Back

A seesaw is an example of a lever, where one side goes up as the other side goes down.
