What is the SI unit of energy?

  1. Gram

  2. Meter

  3. Joule

  4. Kilogram

The correct answer is: Joule

The SI unit of energy is the Joule. This is because the Joule is the standard unit for measuring energy in the International System of Units. A gram is a unit of mass, while a meter is a unit of length, so these options are not correct for energy measurement. Additionally, a kilogram is also a unit of mass, so it is not the correct answer for energy.
