Read each statement below carefully and state with reasons, it is true of false:The average speed of a particle (defined as total path length divided by the time taken to cover the path is either greater or equal to the magnitude of average-velocity of the particle over the same time interval). |

Answer» True, average speed depends upon total path-length which can be equal or more than the magnitude of displacement vector of the particle and average velocity depends upon the displacement vector. Thus, average speed can be equal or greater than the magnitude of average velocity. |
