(6 cards)
What are moments caused by
Forces, but they are not forces themselves
Are they vectors or scalars
They are vectors quantities and have direction, usually constricted to clockwise or anticlockwise
What is the unit for a moment
Newton metre
What is the equation for a moment
Moment=. Force X perpendicular distance from pivot to the force
M (NM)= F (N) XD (M)
What are the keywords used when describing moments on something
- Moments
- Clockwise, anticlockwise
- force
- pivot
- equal
- Distance
- Some
- The weights in newtons
What is the principle of moments
The sum of the anticlockwise moment is equal to the sum of the clockwise moment when the system is in equilibrium
