Question

what is torque? multiple choice a vector quantity describing the rate at which an object rotates per unit time. a scalar quantity describing the twisting force/action acting on an object, causing it to rotate around an axis. a vector quantity describing the product between mass and velocity. a vector quantity describing the twisting force/action acting on an object, causing it to rotate around an axis.

Explanation:

• Option 1: Describes angular velocity, not torque.
• Option 2: Torque is a vector (not scalar) quantity.
• Option 3: Describes momentum, not torque.
• Option 4: Correctly defines torque as a vector quantity for twisting force causing rotation.

Answer:

D. A vector quantity describing the twisting force/action acting on an object, causing it to rotate around an axis. (Note: Assuming the last option is labeled D; adjust label as per actual question's numbering if different.)
