A force can make an object turn about a pivot.
Give the unit of the moment of a force.
State the equation linking moment of a force, force and distance normal to the direction of the force.
A student pushes on the handle of a door with a force of 30 N.
The force acts at right angles to the door.
The handle is 0.80 m from the hinge.
Calculate the moment of the force about the hinge.
State one way the student could increase the moment about the hinge without increasing the force.
Give one other example of a force making an object turn.
