Question

When two objects A and B are moving with different velocities, then the velocity of one object A with respect to another object B is known as :

• A. Positive velocity
• B. Negative velocity
• C. Relative velocity
• D. Linked velocity

Hint:

Relative velocity helps describe how one moving object appears to another moving observer.

Answer 1

The Correct Option is C

Concept: Relative velocity is the velocity of one object as observed from another moving object. It describes how fast one object appears to move with respect to another object. Mathematically: \[ \vec{V}_{AB} = \vec{V}_A - \vec{V}_B \] where:
• \( \vec{V}_{AB} \) = velocity of object \(A\) relative to object \(B\)
• \( \vec{V}_A \) = velocity of object \(A\)
• \( \vec{V}_B \) = velocity of object \(B\)

Step 1: Understand motion with respect to another object.
When two objects move with different velocities, the motion of one object observed from the other is called relative motion.

Step 2: Identify the correct term.
The velocity of object \(A\) with respect to object \(B\) is known as: \[ \text{Relative velocity} \] Hence, the correct answer is: \[ \boxed{(C)\ \text{Relative velocity}} \]
