Moment of Force (Torque) Quiz

Create a scenario where the torque (Moment of Force) on an object is zero.

• The object is not moving.
• The force applied is greater than the object's weight.
• The force applied is in the same direction as the object's axis of rotation.
• The force applied is perpendicular to the object's axis of rotation.

If the force applied is perpendicular to the lever arm, the torque is ________.

• Maximum

• Minimum

• Zero

• None of the above

What is the moment of force or torque?

• The rotational equivalent of linear force

• The amount of force applied to an object

• The distance between two forces

• The rate of change of momentum

Who introduced the concept of torque?

• Albert Einstein

• Isaac Newton

• Archimedes

• Galileo Galilei

Two forces of equal magnitude are applied to a rotating object at a certain distance apart. If the distance between the forces is doubled, what happens to the torque?

• It doubles

• It halves

• It quadruples

• It becomes zero

Apply the concept of torque to explain the behavior of a spinning top.

• The top spins due to the torque provided by the initial twist

• The top spins due to the torque provided by gravity

• The top spins due to the torque provided by friction

• The top spins due to the torque provided by air resistance

If you were to push a door open by applying a force closer to the hinges, what would happen to the torque?

• It would increase

• It would decrease

• It would stay the same

• It would become zero

The moment of force depends on which of the following factors?

• The magnitude of the force

• The distance from the pivot point to the line of action of the force

• The angle between the force and the lever arm

• All of the above

If you were to open a door, where would you apply the force to exert maximum torque?

• Near the hinges

• At the center of the door

• Far from the hinges

• It doesn’t matter where the force is applied
