Verified step by step guidance1
Understand that the International System of Units (SI) defines specific base and derived units for various physical quantities.
Recall that energy is the capacity to do work or produce heat, and it is measured in a specific SI derived unit.
Identify the units given: newton, watt, volt, and joule, and recall what each unit measures:
- Newton (N) measures force.
- Watt (W) measures power, which is the rate of energy transfer.
- Volt (V) measures electric potential difference.
- Joule (J) measures energy or work done.
Therefore, the unit commonly used to measure energy in the SI system is the joule.
