Question

Which of the following has the same dimensions as energy?

Options

Choose one · Correct answer highlighted

Explanation

Energy has dimensions [M L² T⁻²] and unit Joule = N·m = kg·m²/s². Torque = r×F also has [M L² T⁻²] but is vector. Among options, power is [M L² T⁻³], force [M L T⁻²], momentum [M L T⁻¹]. Only torque shares energy dimensions, so Torque is correct.
