Question

A frame of reference moving with constant velocity relative to an inertial frame is also known as what?

• A. Non-inertial frame
• B. Accelerated frame
• C. Inertial frame
• D. Rotating frame

Hint:

All frames moving with {constant velocity relative to each other} are {inertial frames}.

Answer 1

The Correct Option is C

Concept: An inertial frame of reference is a frame in which Newton’s laws of motion hold true. In such frames, objects either remain at rest or move with constant velocity unless acted upon by an external force.
Step 1: Understand the transformation between inertial frames.} If one frame moves with a constant velocity relative to another inertial frame, it also behaves as an inertial frame.
Step 2: Reason for this property.} Because the relative velocity between the frames is constant (no acceleration), Newton’s laws remain valid in both frames. Thus, a frame moving with constant velocity relative to an inertial frame is also an inertial frame.
