The Moment is the product of the force multiplied by the distance from the point an object will turn. In our past classes, we got to understand pivots and how they work. To help you refresh your memory, take up the quiz below and see if you followed the turning effects of forces, and ensure that you get to read up some more on the topic.
Move forward
Move backward
Stop moving
Turn about a fixed point
A point near the hinges and perpendicular to the door
A point near the hinges and parallel to the door
A point far away from the hinges and perpendicular to the door
A point far away from the hinges and parallel to the door
Only if they act on the same point on the object
If they are separated by a distance
When they are balanced by a third force
when their moments about the same point are equal
