Moments (11) Flashcards
What is a moment
Turning effect of a force
Moment equation
Moment = Force x Perpendicular distance
The centre of gravity of an object is the point where all of the __________ appears to _____
Weight
Act
2 ways to increase the stability of an object:
Lowering the centre of gravity
Increasing the area of the base
Law of momentum: For an object to be in _______________ the sum of ____________ moments must be equal to the sum of ________________ moments
Equilibrium
Clockwise
Anticlockwise
The centre of gravity hangs directly _________ the point of suspension
Below
A freely suspended object will swing until its centre of gravity is _____________ below the point of suspension
Vertically
If an object is balance then: Total _______________ Moments = Total ____________ Moments
Total Anticlockwise Moments = Total Clockwise Moments
If the total anticlockwise moments do not equal the total clockwise moments, there will be a ______________ moment. Therefore the object will ________
Resultant
Turn
