Moments 4.5 / 5 based on 2 ratings ? PhysicsForces and MotionGCSEAQA Created by: CharCreated on: 21-05-13 15:14 What is the turning effect of a force called? A moment 1 of 15 How do you work out the size of a moment? M = F x d 2 of 15 What does M stand for? Moment of force = Nm (newton-metres) 3 of 15 What is F? Force in newtons = N 4 of 15 What is d? Perpendicular distance from LINE OF ACTION of the force to the pivot = m (metres)1 5 of 15 What can you do to increase the moment? The force must increase OR the distance to the pivot must increase 6 of 15 Which size is it easier to push on to undo a wheel nut? Long spanner 7 of 15 What does the long spanner increase the distance between? Line of action of the force and the pivot 8 of 15 What makes a job easier? A lever 9 of 15 What is the force called we are trying to move? The load 10 of 15 What is the force applied to the lever? The effort 11 of 15 What does the lever act as? A force multiplier 12 of 15 Which means the effort we apply can be...? Much less than the load 13 of 15 What's an example of how moments might be used in an exam question? Opening a door or a can of paint 14 of 15 What does perpendicular distance actually mean? Shortest distance from the line that the force acts along 15 of 15
