Why does an object falling in the earth's gravitational field reach a steady velocity?
Correct answer: A. Air resistance increases with increase in velocity
- A. Air resistance increases with increase in velocity
- B. The Earth's gravitational field decreases as the object falls
- C. The mass of the object remains constant
- D. The weight of the object increases as it falls
Explanation
When an object falls in the Earth's gravitational field, it eventually reaches a steady velocity, known as terminal velocity. This occurs because of the balance between the force of gravity pulling the object downward and the opposing force of air resistance.

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.
