Question

The instantaneous power in terms of force F and instantaneous velocity v is

• A. P=F.t
• B. P=F.v
• C. $P=F.v^{-1}$
• D. $P=F.v^{-2}$
• E. $P=F.v.t^{-1}$

Answer 1

The Correct Option is B

The instantaneous power \( P \) in terms of force \( F \) and instantaneous velocity \( v \) is given by the formula:

\[ P = F \cdot v \] This is because power is defined as the rate at which work is done, and work is the product of force and displacement. For an instantaneous rate, this relationship simplifies to the product of force and velocity. Therefore, the correct equation for instantaneous power is: \[ P = F \cdot v \] 

Correct Answer:

Correct Answer: (B) \( P = F \cdot v \)
