How to Solve Elevator Problems in Physics (& AP Phys) Classes Apparent Weight and the Normal
4-5 The Elevator 1. An elevator is moving up at a constant velocity of 2.5 m/s, as illustrated in the diagram to the right: The man has a mass of 85 kg. a. Construct a force diagram showing the forces acing on the man. b. What force does the floor exert on the man? 2. The elevator now accelerates upward at 2.0 m/s2. a. Construct a force diagram.
Apparent Weight of an Object in a Lift SPM Physics
According to Newton's second law, the forces acting on you are: ΣF = ma The overall acceleration is up, so the acceleration is positive. There are two forces in action, your weight down (-mg) and the supporting normal force. ΣF = N - mg N - mg = ma N = ma + mg N = m (a + g)

The force that accelerates the elevator comes from the cable of the elevator. And yes, Normal force is present but comes from the floor of the elevator which always exerts the same force of 98 N to balance the baby and prevent it from plummeting to the center of the earth; and this follows the Newton's third law.

The "Elevator Problem" is a classic problem in physics. The situation is this: "You are standing on a bathroom scale in an elevator. You are holding an apple. (Yes, people staring at you.) You weigh 500 Newtons, so your mass is about 50 kg." This assignment is a step-by-step analysis of the elevator problem.

Man In Elevator Problem Cole07 Nov 28, 2006 Elevator In summary, the force exerted by a 65-kg man on the floor of an elevator depends on the conditions of the elevator's motion. When the elevator is stationary, the man exerts a force of 637.65N. When the elevator accelerates upward at 2.3 m/s2, the man exerts a force of 787.15N.

Elevators Problems: Problem (1): An student weighing 550 N stands on a spring scale in a 950-kg elevator (including the person). Just as the elevator starts moving, the scale reads the student's weight as 517 N. (a) What is the magnitude and direction of the elevator's acceleration? (b) Find the acceleration if the scale reads 572 N?

Spread the love. The elevator's free-body diagram has three forces, the force of gravity, a downward normal force from you, and an upward force from the tension in the cable holding the elevator. The combined system of you + elevator has two forces, a combined force of gravity and the tension in the cable. Table of Contents show.

Elevator Problem. This is an application of Newton's second law to the forces felt in an elevator. If you are accelerating upward you feel heavier, and if you are accelerating downward you feel lighter.. For a mass m= kg, the elevator must support its weight = mg = Newtons to hold it up at rest. If the acceleration is a= m/s² then a net.
