Torque is a measure of a force's tendency to produce...

• rotational motion

• momentum

• linear motion

What is the Unit for Torque

• Nm

• N

• W

• J

Torque is the product of a force exerted on an object times the lever arm.

• True 

• False

When an object is experiencing a net torque

• it is in dynamic equilibrium.

• it is in static equilibrium.

• it is rotating.

• it is translating.

Which of the following factors does not affect the torque produced by a force?

• Magnitude of the force

• Distance from the pivot point

• Angle of the force application

• Mass of the object
