Final answer:
Torque is the twisting force on a shaft, defined as the rotational equivalent of a force. It measures how effective a force is in changing or accelerating a rotation.
Explanation:
Torque is the twisting force on a shaft. It is the rotational equivalent of a force, measuring the effectiveness of a force in changing or accelerating a rotation. Torque is defined as t = rF sin θ, where r is the distance from the axis of rotation, F is the force applied, and θ is the angle between the force and the lever arm.
