4 cards from this section. Quick, good the night before a test.
What is the moment of force?
Think of how force can cause rotation.
What is the SI unit for measuring moment?
What unit do we use for measuring force?
What is the formula for calculating the moment of force?
Remember, it's about how much force is applied at a distance.
True or False: The longer the distance from the pivot, the less force is required to create the same moment.
Think about how leverage works.
A force of 40 N is applied at a distance of 0.8 m from a pivot. Calculate the moment of force and explain how changing the position closer or further would affect it.
Use the formula moment = force × distance.
Evaluate how moments work in a seesaw with two children of different weights sitting at different distances from the pivot. Explain how equilibrium is achieved.
Recall that equilibrium occurs when clockwise moments equal anticlockwise moments.
