A man in an elevator ascending with acceleration will conclude that his weight is:
Correct answer: A. Increased
- A. Increased
- B. Decreased
- C. Reduced to zero
- D. Remain Constant
Explanation
As the elevator pushes upward, the downward force, i.e., weight, will appear to increase. Weff = mgeff geff = (g + a)

About Newton's Laws of Motion
Newton’s laws explain inertia, the relation between net force and acceleration, and action-reaction pairs. Questions involve free-body diagrams, balanced and unbalanced forces, F = ma, force as the rate of change of momentum, and identifying genuine third-law pairs, which act on different bodies.
