give an example of a situation in which body has a certain average speed but its average velocity is zero
Answers
WHAT IS VELOCITY?
WHEN A BODY CHANGE ITS POSITION WITH TIME OR U CAN SAY THAT IT IS IN MOTION THAN THE RATE OF CHANGE ITS POSITION IS KNOWN AS VELOCITY. OR WHEN THE BODY IN ITS MOTION CHANGE ITS POSITION VECTOR WITH TIME THAN WE CAN SAY THAT RATIO OF ITS DISPLACEMENT WITH TIME IS KNOWN AS VELOCITY
SOME TIME MOST OF THE STUDENT MISUNDERSTAND AVERAGE VELOCITY AND RELATE IT WITH LIKE THAT....
"AVERAGE VELOCITY IS THE MEAN OF ANY TWO VELOCITY " BUT ACTUALLY ITS NOT.
WHAT IS AVERAGE VELOCITY?
IT SIMPLY THE SUM OF TOTAL DISPLACEMENT
DIVIDE BY TOTAL TIME ELAPSED TO DISPLACE.
WHAT IS AVERAGE SPEED?
IT IS THE RATIO OF TOTAL DISTANCE WITH TOTAL TIME.
A BODY IN MOTION CAN HAVE ZERO AVERAGE VELOCITY BUT CAN NOT HAVE ZERO AVERAGE SPEED.
SO THE CONDITIONS YOU GIVE IS POSSIBLE.
1. WHEN A BODY IN MOTION SUCH THAT ITS INITAL AND FINAL POSITION IS SAME THAN IT HAS ZERO AVERAGE VELOCITY BUT HAVE A NON ZERO AVERAGE SPEED.
BECAUSE TOTAL DISPLACEMENT IS ZERO. BUT TOTAL DISTANCE IS NON ZERO
Answer:
the situation when the initial and final position of the body is same then this case will arise
happy diwali in advance
