If the acceleration of a body in one inertial frame is zero, its acceleration in any other inertial frames is
Correct answer: B. Zero
- A. Increased
- B. Zero
- C. Decreased
- D. Increased and then decreased
Explanation
According to the principle of relativity, if an object is at rest or moving with a constant velocity in one inertial frame, it will also be at rest or moving with a constant velocity in any other inertial frame. Inertial frames are reference frames in which an object moves with a constant velocity unless acted upon by an external force.Since acceleration is the rate of change of velocity, if an object has zero acceleration in one inertial frame, its velocity is constant. In another inertial frame, the object's velocity may be different, but its acceleration will still be zero if the velocity is constant.

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.
