Lever

Science

Not quite remember

I easily remember

The use of lever

A lever is used to lift or to pry an object

Three parts of lever

Load, fulcrum and force

Load

The weight of an object

Fulcrum

Is a point on a beam that functions to support and balance the beam

Force

The push and pull action that gives effect to an object

Examples of application of lever in daily life

Sweeping, pulling out a nail & gripping ice

The relationship between the load, fulcrum and the force on a lever

The closer the load from the fulcrum, the lesser the force that is needed to lift the load

The consequences when the load is far from the fulcrum

More force is needed to lift the load

The consequence when the load is closer to the fulcrum

Lesser force is needed to lift the load
