What is the turning effect of a force equivalent to |
The moment of the force |
|
What is the unit for moment |
Newton metres (Nm) |
|
What is the equation for moment |
Moment (Nm) = Force (N) X distance (m) |
|
Is the unit for force Newton metre or newton's per metre |
Newton metre |
|
Define pivot |
The centre of an object that makes it move |
|
We cannot calculate the moment if we don't use the perpendicular distance True or false |
True |
|
What is the perpendicular distance |
The distance between the action of force and the pivot |
|
The force of action should form an L shape with the object where the pivot is for it to be the perpendicular TRUE OR FALSE EXPLAIN WHY |
True because this shows that it is 90 degrees and the perpendicular distance can be used in moment equation |
|
What does the moment equation calculate |
The size of a moment |
|
What can forces be represented as |
Vectors |
