SUMMARY
The formula for calculating power (P) in the context of kinetic energy is given by P = 1/2 Aρv³, where P is indeed measured in watts. The variables are defined as follows: A is the cross-sectional area in square meters (m²), ρ is the density in kilograms per cubic meter (kg/m³), and v is the velocity in meters per second (m/s). The discussion confirms that using metric units for these variables ensures accurate calculations of power.
