A frame will be inertial, if it moves with respect to another inertial frame with a constant :-

Options

A. Linear velocity
B. Angular velocity
C. Linear acceleration
D. All of the above

Answer

To solve the question, we need to understand the conditions under which a frame of reference is considered inertial.

### Step-by-Step Solution:

1. **Definition of Inertial Frame**: An inertial frame is one in which Newton's laws of motion hold true. This means that objects in this frame either remain at rest or move at a constant velocity unless acted upon by a net external force.

2. **Relative Motion Between Frames**: If one inertial frame is moving with respect to another inertial frame, the motion must be uniform. This means that the relative velocity between the two frames must be constant.

3. **Constant Velocity**: For a frame to be considered inertial, it should not be accelerating. Therefore, if Frame A is moving with respect to Frame B, and both are inertial, Frame A must be moving with a constant velocity relative to Frame B. This means that the acceleration of Frame A with respect to Frame B must be zero.

4. **Conclusion**: Thus, a frame will be inertial if it moves with respect to another inertial frame with a constant velocity. This implies that there is no relative acceleration between the two frames.

### Final Answer:
A frame will be inertial if it moves with respect to another inertial frame with a constant **velocity**.
