Answer»

(a) Work is said to be done by a forte only when the body moves.

(b) Work done = Force × distance moved in direction of force.

(d) The S.I. unit of energy is joule.

(e) The potential energy of a body is due to its state of rest or position and kinetic energy of body is due to its state of motion.

(f) Gravitational potential energy U = mass × force of gravity on unit mass × height.

(g) Kinetic energy = 1/2 × mass × (speed)²

(h) Power P = work done/time taken.

(i) The S . i. unit of power is watt

(j) 1 H.P. = 746 W
