Show that the instantaneous power is dot product of force and velocity.

Power is vector product of force and velocity.

Show that power is the product of force and velocity.

Define instantaneous power.

Statement A: An engine A can perform a given work in 1 hr and engine B can perform the same work in 1/2 hr. then B has greater power than A. Statement B: Power is the dot product of force and velocity

Define instantaneous power. Express it as the scalar product of force and velocity vectors.

Instantaneous Velocity

Express instantaneous power in terms of vecFandvecv .
