Gcse Physics Module 3 Moments 4.0 / 5 based on 3 ratings ? PhysicsForces and MotionGCSEAQA Created by: Hannah ChappatteCreated on: 09-01-13 19:24 What is a 'moment'? Measurement of the turning effect of the force on an object 1 of 7 What is the 'effort'? Force applied 2 of 7 How do you increase the moment of a force? Increase the force itself or the distance from the line of action to the pivot 3 of 7 What is the centre of mass? The point where it's mass may be thought to be concentrated 4 of 7 What does it mean to be in 'equilibrium'? When a suspended object's centre of mass is directly beneath the point of suspension. 5 of 7 How is stability increased? By making its base as wide as possible and its centre of mass as low as possible 6 of 7 Why will and object fall over? Because its line of action of its weigh is outside its base (if its resultant moment is NOT zero) 7 of 7
