Turning Forces Flashcards
1
Q
What happens when you apply a force to something?
A
It might turn about a fixed point.
This fixed point is known as the pivot.
The turning effect is called a moment.
2
Q
Draw and label the force and pivot
A
N/a
3
Q
When does the moment increase?
A
The moment (turning force) increases if the force is larger or if the distance to the pivot increases.
4
Q
How to find the size of a moment?
A
M = F x d
M = moment of the force (Nm)
F = force (N)
d = perpendicular distance from the line of action of the force to the pivot (m)
5
Q
How is perpendicular distance measured?
A
Perpendicular distance is measured along a line that is at a right angle to the direction of the force.
