Torque Practice

Front

What is torque?

Back

Torque is a measure of the rotational force applied to an object, calculated as the product of the force and the distance from the pivot point.

Front

What is the formula for calculating torque?

Back

Torque (τ) = Force (F) × Distance (r) × sin(θ), where θ is the angle between the force vector and the lever arm.

Front

What does it mean when total torque is zero?

Back

When total torque is zero, the object is in rotational equilibrium, meaning it will not rotate.

Front

What is the difference between clockwise and counterclockwise rotation?

Back

Clockwise rotation moves in the same direction as the hands of a clock, while counterclockwise rotation moves in the opposite direction.

Front

If the total torque to the left is greater than to the right, which way will the object turn?

Back

The object will turn in the direction of the greater torque, which in this case is to the left.

Front

What happens if the total torque to the left equals the total torque to the right?

Back

If the total torque to the left equals the total torque to the right, the object will not rotate and will remain in its current position.

Front

How does distance from the pivot point affect torque?

Back

Increasing the distance from the pivot point increases the torque for the same amount of force applied.

Front

What is a lever arm in the context of torque?

Back

The lever arm is the perpendicular distance from the pivot point to the line of action of the force.

Front

What is the unit of torque?

Back

The unit of torque is the Newton-meter (Nm) in the SI system.

Front

How does the angle of force application affect torque?

Back

The angle affects the effective component of the force that contributes to torque; maximum torque occurs when the angle is 90 degrees.
