Calculating turning force
Calculating balanced forces

Turning Force
Can you use this basic physics to calculate the mass of the ruler?
find the centre point of the ruler and mark it
balance two equal masses at different points
what do you notice?
balance two unequal masses
what do you notice?
Work out the turning forces of the two masses
Do it now
What does this mean?
How does the distance from the pivot affect the force?
How does force change with the distance from the pivot?
What do you notice about the turning forces when the ruler is balanced?
