Velocity or speed is measured and indicated in: _____________?
Show answer Hide answer
Answer: D. Km/hour
Explanation
Velocity and speed in physics are commonly measured and expressed in kilometers per hour. This standard metric unit indicates the distance traveled by an object relative to time elapsed. Sports science applications rely on this unit to quantify the speed of moving objects like balls. Speed is a scalar quantity measuring how fast something moves, while velocity includes direction. The International System of Units uses meters per second, but kilometers per hour is widely used in sports. Radar guns and tracking technology measure athletic performance metrics in these standard units.
Coaches and analysts track the speed of serves and spikes to evaluate player power and performance. Physics education uses sports examples to help students understand the practical application of velocity. Reporting athletic statistics in familiar units makes performance data accessible to sports fans. KM/sec represents an excessively large unit of speed that is not used for human athletic movements. CM/Hiur contains a typographical error and uses centimeters which is too small for standard speed. Newton is a unit of force in physics rather than a measure of velocity or speed.
