# Elevator Questions: Describe 2 Forces

• Jordash
In summary, while standing in an elevator moving at a constant speed from the first to tenth floor and then back to the first, there are two important forces that act on you: gravity and the force exerted by the elevator. The elevator may also experience a fictitious force, but this does not directly act on you.

## Homework Statement

You are standing on the ﬂoor of an elevator that starts, at rest, at the ﬁrst ﬂoor of a building and then moves at constant speed to the tenth ﬂoor where it stops. Then you reverse the motion, ending where you started at the ﬁrst ﬂoor.

Describe the two important forces that act on you during this motion.

## The Attempt at a Solution

One of the Forces would be gravity right? What is the other one?

Would the elevator ever slow up or speed up? Would you feel it? If so what might that force be?

What are you in contact with?

## 1. What are the two forces involved in elevator movement?

The two forces involved in elevator movement are the gravitational force and the electromagnetic force.

## 2. How does the gravitational force affect elevator movement?

The gravitational force, also known as weight, pulls the elevator and its passengers towards the center of the earth. This force is responsible for the downward movement of the elevator.

## 3. What is the role of the electromagnetic force in elevator movement?

The electromagnetic force is responsible for the upward movement of the elevator. It works by using an electric motor to pull the elevator up using cables and pulleys.

## 4. How do these forces work together to move the elevator?

The gravitational force pulls the elevator down while the electromagnetic force counters it by pulling the elevator up. These forces work together to create a balanced movement of the elevator.

## 5. Are there any other forces involved in elevator movement?

Aside from the gravitational and electromagnetic forces, there are also other forces involved in elevator movement such as friction, air resistance, and the weight of the elevator itself. However, these forces are relatively small and do not significantly affect the movement of the elevator.
