A feather initially at rest, is released in a vacuum 12m above the surface of the earth. Which of the following statements is correct?
Correct answer: B. The acceleration of the feather remains constant during the fall
- A. The maximum velocity of the feather is 9.8 m/s
- B. The acceleration of the feather remains constant during the fall
- C. The acceleration of the feather increases during the fall
- D. The acceleration of the feather decreases until terminal velocity is reached
Explanation
In a vacuum, near the surface of the Earth, the acceleration due to gravity remains approximately constant at 9.8 m/s2. As long as the feather is in free fall without encountering any significant air resistance or external forces, its acceleration will remain 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.
