Work has the dimension as that of:
Correct answer: A. Torque
- A. Torque
- B. Momentum
- C. Power
- D. Angular momentum
Explanation
Work and torque have the same dimensions, but they represent different physical quantities: work is related to the energy transferred to or from an object, while torque is related to the rotational force applied to an object. The dimension of work is given by [ML2T −2]. Torque, which is the rotational equivalent of force, also has the same dimension of [ML2T −2]. Therefore, the dimension of work is the same as the dimension of torque.

About Work
Work is done when a force produces displacement, with its value determined by the component of force along the displacement. The topic covers positive, negative and zero work, work by variable forces from force-displacement graphs, and the connection between net work and change in kinetic energy.
