It is a diagram which shows only the object and the forces acting on it.
2
Q
How do you represent forces?
A
Using arrows
3
Q
How do you draw the arrows?
A
Start them from approximately where the force starts acting and point them away from the object.
4
Q
How do you represent the magnitude of the force?
A
You make the arrow longer if the magnitude is higher.
5
Q
What is magnitude?
A
Size
6
Q
What should you do after drawing the arrow correctly?
A
You should label the arrow with the name of the force.
7
Q
Can you add more than one arrow showing forces on a single diagram?
A
Yes
8

A
Draw an arrow going upwards from the bottom of the object at 90 degrees from the surface (the normal line) and label it ‘normal contact force’.
