What is the name of the force applied to a lever?
Effort
Pivot
Load
What will be the effect of using a longer lever to apply a force further from the pivot?
The turning effect will increase
There will be no difference in the turning effect
The turning effect will decrease
A gear rotates clockwise. What is the direction of a touching gear, seen from the same direction?
Clockwise
No rotation

Two identical weights are attached to opposite ends of a beam. Both are 1 m from the pivot. What happens if the right hand weight is moved closer to the pivot?
The beam rotates clockwise
The moment of the left hand weight decreases
The beam rotates anticlockwise
