P10 Momentum And Moments Flashcards
1
Q
To calculate momentum:
A
Mass x velocity
2
Q
What is a moment?
A
The turning effect of a force, depending upon the size of force and where it is applied.
3
Q
To calculate the moment:
A
Applied force x perpendicular distance of force from the fulcrum
Force x distance
4
Q
How does using a lever require less effort (force)
A
The perpendicular distance from the fulcrum is larger, meaning the moment is larger, and less force is needed.
