Moment of a force

Moment = force / distance from pivot

• True

• False

The greater the force, the greater its turning effect.

• True

• False

The further the force is from the pivot, the greater its turning effect.

• True

• False

What is the moment acting on the left side of the pivot?

• 2 Nm

• 200 Nm

• 0.2 Nm

What is the moment acting on the right side of the pivot?

• 2 Nm

• 20 Nm

• 200 Nm

• 0.2 Nm

The beam is balanced.

• True

• False

A force of 4 N acts on a lever 2 m from the pivot. What is the moment?

• 8 Nm

• 6 Nm

• 2 Nm

• 3 Nm

One way to increase the turning force on a spanner is to:

• Use a shorter spanner

• Use a longer pivot

• Use a longer spanner
