Question

(1) VAB = VB-VA
(1) VAB - VA-VB
which of the
above is correct?​

Answer 1

Answer:

VAB=VA-VB. is the correct dude !!!

thank you !!!!!

Answer 2

The correct answer is (2) $V_{AB} =V_{A} -V_{B}$

Relative velocity definition:

• Relative velocity means that velocity where the velocity of an object B in the rest frame of another object A. It can also be understood as the determination of the velocity of a body with reference to some other object present."
• It is taken as the rate at which the relative position or location of one object changes with respect to some other object over time.

• Practically, we can say that every motion is relative because it must be observed in relation to something.

Explanation:

For writing the Relative velocity of A with respect to B, we write it as the difference between the velocity of A and the velocity of B in vector form.

Mathematically,

$V_{AB} =V_{A} -V_{B}$

(the observer who is being observed is kept first and the one with respect to which it is observed is kept second)

where,

$V_{AB}=$ Relative velocity of body A with respect to B

$V_{A}=$ Velocity of A

$V_{B}=$ Velocity of B

Hence, the answer is (2) $V_{AB} =V_{A} -V_{B}$
