4. moments 3.0 / 5 based on 1 rating ? PhysicsForces and MotionGCSEAQA Created by: Vicky FursdonCreated on: 09-03-13 11:24 What is the formula for moments? Force X the perpendicular distance from the picot point 1 of 10 How can you get the maximum moments from a spanner? If the force is applied at a right angle (perpendicular) 2 of 10 If the anti-clockwise moments is equal to the clockwise moment what is happen to the object? It won't move 3 of 10 What do levers do? The increase the distance from the pivot so less force is needed 4 of 10 Give 2 examples of simple lever? Wheelbarrows and scissors 5 of 10 What is needed for an object to be stable? It needs a low centre of mass and a wide base 6 of 10 If the anti-clockwise moments isn't the same as the clockwise moments what is happening? There is a resultant moment acting on the object 7 of 10 What happens to an object if it's line of action of the weight goes outside of the base? This causes a resultant moment, so the object will tip over 8 of 10 What is the formula for time period? 1/frequency of the pendulum (Hz) 9 of 10 What does the time period of a pendulum depend on? The length on the sting it is suspended from 10 of 10
