Step 1: Define power in terms of work and time. Power (P) is the rate at which work (W) is done or energy is transferred over time (t). P = (W)/(t) Step 2: Define work in terms of force and displacement. Work (W) is the product of force (F) and displacement (d). W = F · d Substitute this into the power equation: P = (F · d)/(t) Step 3: Define force in terms of mass and acceleration. Force (F) is the product of mass (m) and acceleration (a). F = m · a Substitute this into the power equation: P = (m · a · d)/(t) Step 4: Express the fundamental SI units for each quantity. • Mass (m): kg • Acceleration (a): m/s^2 (since acceleration is change in velocity over time, and velocity is change in displacement over time, a = m/ss = m/s^2) • Displacement (d): m • Time (t): s Step 5: Substitute the fundamental units into the expression for power. P_units = (kg) · (m/s^2) · (m)(s) P_units = kg · m^2s^2 · s P_units = kg · m^2s^3 P_units = kg m^2 s^-3 Thus, the fundamental units of power are kg m^2/s^3. The fundamental units of power are kg m^2/s^3.
