Which of the following has no acceleration:
Correct answer: C. A luggage in flying airplane
- A. Man driving a car on busy road
- B. Rock rolling down a mountain
- C. A luggage in flying airplane
- D. A car on a rough road
Explanation
If an aircraft is traveling at a steady speed, luggage in a flying airplane can be seen as not accelerating. On the other hand, strictly speaking, the luggage would also accelerate if the airplane changed its course or speed. But the velocity of the plane stays the same, in general, as there is no hindrance in the motion of a plane as the other things have.

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.
