Physics · Rotational Mechanics
Which of the following statements regarding torque and rotational motion are correct? 1. Torque = Force × Perpendicular Distance from the Axis of Rotation. 2. A greater moment arm increases the generated torque for a given force. 3. Torque is measured in Joules (J) as a standard SI unit of mechanical work. 4. Angular velocity decreases if the moment of inertia increases, provided net external torque is zero. 5. In diving, extending the arms outwards reduces total angular momentum.
