Question

You walk to school and then walk home again. What is your average velocity for the whole journey? Explain

Answer 1

Answer:

Zero

Explanation:

the displacement is constant

Answer 2

Average velocity would be ZERO

Explanation:

Average velocity = displacement / time

• Displacement is the distance between initial and final point .

• be careful it is  displacement not the distance .

as you walk back from the school right back to the home from where you begin your initial and final points become same so your  displacement becomes ZERO ,

although you covered the distance but eventually you returned back to the same point .

To understand easily , its like you moved some positive  and than some negative which adds up to zero displacement
