What is a moment?
The turning affect of a force
M =
F x d
What does F stand for in M = Fxd
Force
What are moments measured in
Nm
What does d stand for in M = Fxd?
The perpendicular distance from the line of action of force to the pivot
For an object to be balanced on a pivot…
The clockwise and anticlockwise moments must be equal
If the size of the anticlockwise moment is bigger than the clockwise moment on a seesaw…
The seesaw is going to pivot in an anticlockwise direction
diagram to work out line of force & using it in equation
