Question

2. What is retardation? How does it affect the speed?
3. Can speed of a body vary with its velocity constant? Explain.
​

Answer 1

Answer:

2.Retardation is the acceleration which acts opposite to the direction of the motion of the body which causes decrease in the velocity of the moving body. Thus it slows down the moving body. Velocity is speedand direction. .

3.No, a body can not have its velocity constant, while its speed varies. Rather, it can have its speed constant and its velocity varying. ... Change of speed.

Answer 2

Answer:

second questions answer

third question answer:

no, a body can not have it velocity Constant while its speed varies. the velocity of an object can be changed by change of speed and change of direction
