Balanced Moments And Levers Flashcards
1
Q
When will an object not turn?
A
When the anti-clockwise moments are equal to the clockwise moments
2
Q
What do levers do?
A
Use the idea of balanced moments and make it easier for us to do work e.g. Lift an object
3
Q
What does the amount of force needed to produce a particular moment depend on?
A
The distance the force is applied from the pivot
4
Q
What do levers increase ?
A
The distance from the pivot at which the force is applied so less force is needed to get the same moment
5
Q
Why are levers known as force multipliers?
A
They reduce the amount of force that is needed to get the same moment by increasing the distance
6
Q
What are three examples of levers?
A
Wheelbarrows
Scissors
Long sticks
