Final answer:
The SI units for area, mass, speed, density, weight and energy are square meters, kilograms, meters per second, kilograms per cubic meter, Newtons and Joules respectively.
Step-by-step explanation:
The SI unit of the following quantities:
- Area is measured in square meters (m^2).
- Mass is measured in kilograms (kg).
- Speed is measured in meters per second (m/s).
- Density is measured in kilograms per cubic meter (kg/m^3).
- Weight is measured in Newtons (N).
- Energy is measured in Joules (J).
These are the standard units in the International System of Units (SI) used globally in scientific contexts.
