The power of an agent at any instant is equal to the dot product of its --------- and --------vectors at that instant.

Vector - Dot Product

Assertion: The instantcous power of an agent is measured as the dot product of instaneous velocity and the force acting on it at that instant. Reason: The unit of instaneous power is watt.

The slope of work-time curve at any instant gives

For a moving body at any instant of time

Which of the following statements is /are correct ? I.Average speed over a finite interval of times is greater or equal to the magnitude of the average velocity. The instantaneous speed at an instant is equal to the magnitude of the instantaneous velocity at that instant.

The distance traversed by a moving particle at any instant is half of the product of its velocity and the time of travers. Show that the acceleration of particle is constant.

According to superposition principle, the………….at any instant is equal to…………of the displacements due to………..at that instant.
