Speed and Velocity: Speed is the rate at which a body moves. It has, nothing to do with the direction in which the body moves and, hence, it is a scalar quantity. It is measured by the distance covered by a body in unit time. Thus, Speed = Distance Covered / Time Taken When a body describes equal distances in equal intervals of time, it is said to have uniform speed but when it describes equal distances in unequal intervals of time or unequal distances in equal intervals of time its speed is said to be variable. In the C.G.S. … Continue reading Speed and Velocity
