In a classroom discussion about the measurement of work and energy, students are asked to identify the correct SI unit and dimensional formula for these quantities. Which option best represents units for both work or energy?
joule and \(ML^2T^{-2}\)
The SI unit of work or energy is the joule, with dimensional formula \(ML^2T^{-2}\).
Watt (power), pascal (pressure) and newton (force) have different units and dimensional formulas, not those of work or energy.
Hence, 'joule and \(ML^2T^{-2}\)' is the correct answer.
