Understanding Torque Concepts Quiz

What is the definition of torque in physics?

• Torque is the force that causes an object to move in a straight line.

• Torque is the measure of the force that can cause an object to rotate about an axis.

• Torque is the energy required to move an object from one point to another.

• Torque is the speed at which an object rotates around an axis.

Which of the following conditions must be met for an object to be in rotational equilibrium?

• The net force acting on the object must be zero.

• The net torque acting on the object must be zero.

• The object must be rotating at a constant speed.

• The object must be at rest.

Which of the following factors does NOT affect the torque applied to an object?

• The magnitude of the force applied.

• The distance from the axis of rotation to the point where the force is applied.

• The angle at which the force is applied.

• The mass of the object.

• 5 Nm

• 10 Nm

• 20 Nm

• 0 Nm

How does increasing the distance from the axis of rotation affect the torque, assuming the force and angle remain constant?

• It decreases the torque.

• It increases the torque.

• It has no effect on the torque.

• It doubles the torque.

In which scenario is the torque zero?

• When the force is applied perpendicular to the lever arm.

• When the force is applied parallel to the lever arm.

• It decreases.

• It increases.

• It remains the same.

• It becomes zero.

Which of the following best describes the role of torque in rotational motion?

• Torque is responsible for linear acceleration.

• Torque is responsible for changes in rotational speed.

• Torque is responsible for maintaining constant rotational speed.

• Torque is responsible for stopping rotational motion.

What happens to the torque if the force applied is doubled while the distance and angle remain constant?

• The torque is halved.

• The torque remains the same.

• The torque is doubled.

• The torque becomes zero.
