SUMMARY
The calculation of the normal force on a person in an accelerating elevator involves understanding the forces acting on the individual. The correct expression for the normal force when the elevator is accelerating upwards is given by m(g + a), where m is the mass of the person, g is the acceleration due to gravity, and a is the upward acceleration of the elevator. Conversely, if the elevator is moving downward with an upward acceleration, the normal force is calculated as m(g - a). This analysis is essential for solving problems related to dynamics in non-inertial reference frames.
