Effects of Forces
- Mass and Weight
- 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
- Pressure in Gases
- More gas
above you
higher the
pressure
- Less pressure higher up
- More pressure lower down
- See example
