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.

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 with less effort.

What is a wedge?

Back

A wedge is a simple machine that is used to separate two objects or portions of an object, often by applying force to the wide end.

Front

What is a screw?

Back

A screw is a simple machine that consists of a cylindrical shaft with a helical ridge, used to hold objects together or lift materials.

How does a door knob function as a wheel and axle?

Back

A door knob functions as a wheel and axle because turning the knob (wheel) rotates the spindle (axle), allowing the door to open.

What is mechanical advantage?

Back

Mechanical advantage is the factor by which a machine multiplies the force put into it, making work easier.
