1.	Under which condition is the magnitude of average velocity equal to average speed
Answer» Average velocity would be equal to average speed when the total\xa0distance\xa0travelled equals the net displacement of a particle. This happens when a particle moves along a straight line in a fixed direction. A n s w e r :Average velocity would be equal to average speed when the total distance travelled equals the net displacement of a particle. This happens when a particle moves along a straight line in a fixed direction. Speed is a scalar quantity having only magnitude and no direction while velocity is a vector quantity having magnitude and direction both.The magnitude of average velocity of an object equal to its average speed when the motion of the object will be straight and unidirectional.As, speed is scalar quantity and velocity is a vector quantity, so the object is required to move in straight line with same or constant direction.
