J

Define This Formula

Work Formula

Work = Force x Distance

Define the SI Unit for Force

Newton

N

Define Weight

The pull of earth on an object

Define the SI Unit for Weight

Newton

N

Define Mass

The amount of matter in an object

Define the SI Unit for Mass

Kilogram

kg

Differentiate between weight & mass

Weight can change

Mass stays constant

Define this Formula

Converting Weight to Mass

Weight = Mass x 10

Define Moment of Force

The circular motion of force

Define Levers

A rigid body that is free to move about a fixed point

Define Pressure

The amount of force acting on an area

Define the SI unit for Pressure

Newtons per square meter / Pascal

N/m², Nm^-2

Define This Formula

Pressure Formula

Pressure = Force / Area

Define Power

The rate at which work is done

Define the SI Unit for Power

Watt

W

Define This Formula

Power Formula

Power = Work Done / Time Taken
