The turning effect of a force is called its moment 1 of 11 How do we work out the size of a moment? M = F x D 2 of 11 What does M stand for? Moment of force in newton metres, Nm 3 of 11 What does F stand for? Force in newtons, N 4 of 11 What does D stand for? Distance from line of action of the force to pivot 5 of 11 How do you increase a moment?(2) Either increase force, or increase distance from pivot 6 of 11 How is it easier to undo a wheel-nut, long or short spanner? Long 7 of 11 Why? Long spanner increases distance between line of action of force and pivot 8 of 11 When using levers, what is the force we are trying to move called?
