Define the following terms negative acceleration average velocity average velocity and average speed |
|
Answer» Negative acceleration is the acceleration in the OPPOSITE direction which change the velocity by decreasing the magnitude of velocity that is delat (v) is always -v .The negative acceleration known as retardation .2 .Average velocity of an object is it's total DISPLACEMENT divided by total time taken . In other WORDS it is the rate at which an object change its POSITION from one place to another . Average velocity is the vector quantity .3. The average speed of an object is the total distance covered by a body divided by the elapsed time to cover that distance . It's scalar quantity which means it is defined only by magnitude .Explanation:Hope this ANSWERS will help you#Follow me ✌️ |
