Question

Define the following terms negative acceleration average velocity average velocity and average speed

Answer 1

Answer:

1. 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 .
