If we are moving with a constant velocity frame, then the inertial state is the same as:
Correct answer: A. Rest frame
- A. Rest frame
- B. Accelerating frame
- C. Non-inertial frame
- D. All of these options are correct
Explanation
An object moves at a constant velocity unless acted upon by an external force. In such a frame, an object is observed to have no acceleration when no forces are acting on it. If a reference frame moves with constant velocity relative to an inertial reference frame, it is also an inertial reference frame.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
