Levers in Physics

Front

Example of mechanical advantage

Back

Levers are examples of mechanical advantage.

Front

Function of a lever

Back

A lever functions to multiply the mechanical force applied to an object.

Front

Calculation of lever function

Back

The calculation for finding out how a lever functions is based on mechanical advantage.

Front

Load in the context of levers

Back

Load refers to the weight or resistance that is moved by the lever.

Front

There are three classes of lever.

Back

Three classes of lever are defined based on the position of the fulcrum, effort, and load.

Front

Diagram of a first class lever showing force effort (F) and load (W).

Back

This diagram illustrates the mechanics of a first class lever.

Front

Diagram of a second class lever

Back

Illustrates the arrangement of force, load, and pivot in a second class lever.

Front

Role of distance in mechanical advantage

Back

Greater distance moved by effort results in smaller effort needed.

Front

Lever mechanics in simple machines

Back

Utilizes mechanical advantage to move loads efficiently.

Front

A lift of 1m high needs to be pulled downwards 1m.

Back

To lift an object 1 meter high with a pulley, pull the rope down 1 meter.
