  • Elevator Problem

    342262 Weight in an elevator The weight of a book was measured using a scale. The scale showed 15N. Next, the book and the scale were placed in an elevator that does not show the floor number.

  • Weight Gain in an Elevator

    W = mg - ma is the equation for the apparent weight of a body in an elevator. Here, mg = 120 lbs, ma = m(-2g) = -2 mg = -240 lbs So, W = mg - ma = 120 - (-240) = 360 lbs. The weight gain in an elevator is determined using Newton's Laws.

  • Newton's Laws of Motion

    Prob. 34 : When a person is accelerating in an elevator, his/her apparent weight is given by : W' = m(g + a) where m = real mass, a = acceleration of the elevator. +ve sign is for acceleration upwards and -ve sign for downwards.
