Which of the following pairs correctly matches a physical quantity with its SI unit?

Energy- Newton

Force – Joule

Power- Watt

Velocity-m/s2

Power is correctly matched with its SI unit, the Watt (W). The other pairs are incorrect as follows:

Energy is measured in Joules (not Newtons).
Force is measured in Newtons (not Joules).
Velocity is measured in meters per second (m/s), not meters per second squared (m/s²), which is a unit of acceleration.
