2 different things
Mass
Amount of substance in an object (kg)
Weight
Measurement of force on object (N)
Weight 10 times bigger
On earth 1 kg of mass is equal to 10 N
Gravitational Field strength(g)
W=mXg
Turning Moments and Equilibrium
Force applied on object that can turn
Distance from pivet x force
When in equilibrium moments are balanced
Principle of Moments
See example on next page
Pressure
Effect of pressure being excerted over a force
P=F A
Pressure units are N/m
For m the pressure unit is Pa
Pressure in Liquids
Increase the further down you go
See exmaples
