Power is defined as the rate of change of work. Hence, P = dW/dt. Instantaneous power = Force x instantaneous speed. Average power = total work / total time.

Expression for Power:
Power is defined as the rate at which work is done or energy is transferred. The correct expression for power is given by:
a) P = dW/dt
Explanation:
- Power: Power is the rate at which work is done or energy is transferred.
- Work: Work is defined as the displacement of an object in the direction of the force applied.
- Expression: The expression for power is derived from the work-energy theorem, which states that the work done on an object is equal to the change in its kinetic energy.
- Derivation: The derivative of work with respect to time gives us the power, as power is the rate of change of work or energy.
- Mathematical Representation: Therefore, the correct expression for power is P = dW/dt, where P is power, W is work, and t is time.
In conclusion, the expression P = dW/dt represents the correct mathematical relationship between power, work, and time. This formula is essential in physics to calculate the rate at which energy is transferred or work is done in a system.
