MF - Chapter 3: Torque and Rotational Motion

What is the definition of torque?

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

• Torque is the measure of the force that can cause an object to shrink in size.

• Torque is the measure of the force that can cause an object to move in a straight line.

• Torque is the measure of the force that can cause an object to change color.

How do you calculate torque?

• Torque = Power x Time

• Torque = Mass x Acceleration

• Torque = Force x Distance

• Torque = Work / Time

Explain the relationship between torque and rotational motion.

• Torque is inversely proportional to the linear velocity of an object in rotational motion.

• Torque has no effect on the rotational motion of an object.

• Torque is only relevant in linear motion, not rotational motion.

• Torque is directly proportional to the angular acceleration of an object in rotational motion.

Give an example of torque in a mechanical system.

• The weight of an object

• The force applied to a wrench to tighten a bolt.

• The speed of a moving car

• The temperature of a room

How does torque affect levers?

• Torque increases the weight of levers

• Torque has no effect on levers

• Torque affects levers by determining the rotational force applied to an object.

• Torque causes levers to move in a straight line

What is the relationship between torque and angular acceleration?

• Torque is inversely proportional to angular acceleration.

• Torque has no effect on angular acceleration.

• Angular acceleration is not related to torque.

• Torque is directly proportional to angular acceleration.

Define torque in the context of physics.

• Torque is a measure of volume in physics.

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

• Torque is a measure of speed in physics.

• Torque is a measure of temperature in physics.

Calculate the torque produced by a force of 10 N applied at a distance of 5 meters from the pivot point.

• 25 Nm

• 50 Nm

• 40 Nm

• 15 Nm

How does torque contribute to the motion of a spinning object?

• Torque has no effect on the spinning object

• Torque causes the spinning object to rotate around an axis.

• Torque causes the spinning object to shrink in size

• Torque makes the spinning object stop moving

Discuss the importance of torque in machinery.

• Torque only affects small machines, not large industrial equipment.

• Torque is irrelevant in machinery operations.

• Torque is essential in machinery as it is the rotational force that drives the movement of components.

• Torque is only important in stationary machinery, not in moving parts.
