Flashcard - APP1 Torque

Front

What is the unit for Torque?

Back

Nm (Newton-meter)

Front

What happens when an object is experiencing a net torque?

Back

It is rotating.

Front

What is the formula for calculating torque?

Back

Torque = Force x Lever Arm Length.

Front

What is the relationship between torque and rotational motion?

Back

Torque causes an object to rotate around an axis.

Front

What is the lever arm in the context of torque?

Back

The perpendicular distance from the axis of rotation to the line of action of the force.

Front

If a force is applied at an angle, how do you calculate the effective torque?

Back

Effective Torque = Force x Lever Arm x sin(θ), where θ is the angle between the force and the lever arm.

Front

What is static equilibrium in terms of torque?

Back

An object is in static equilibrium when the net torque acting on it is zero.

Front

What is dynamic equilibrium in terms of torque?

Back

An object is in dynamic equilibrium when it is moving with constant angular velocity and the net torque is zero.

Front

How does increasing the distance from the axis of rotation affect torque?

Back

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

Front

What is the effect of applying force in the opposite direction of rotation?

Back

It creates a negative torque, which opposes the rotation.
