In 1857, the originator of the escalator was Nathan Ames, who sought to create a means for assisting the ill with a home version. His model was never produced. In 1889, Leamon Souder patentedÊanother model. Both Jesse Reno and George Wheeler patented different walking stairways in 1892. Finally, Wheeler sold his inventionÊ to Charles Seeburger, who along with the Otis Elevator Company produced the first working model in 1899 .

What is happening if a person is walking up the steps of a downward moving escalator at a constant speed?

If a person is walking up the steps of a downward moving escalator at a constant speed, they will feel as if they are walking on a stationary surface. The person's upward motion will cancel out the downward motion of the escalator, resulting in no net movement relative to the escalator itself.


What type of transformation is taking place when you travel up an escalator?

The type of transformation taking place when you travel up an escalator is a translational motion, where an object moves from one point to another in a straight line.


Which of these is true of a person walking up the steps of a downward-moving escalator at a constant speed?

If a person is walking up the steps of a downward-moving escalator at a constant speed, then their speed relative to the ground will be the sum of their walking speed and the speed of the escalator. This means they will ascend the steps slower compared to if the escalator was stationary or moving upwards.


What is true of a person walking up the steps of a down ward moving escalator at a constant speed?

If a person walks up the steps of a downward moving escalator at a constant speed, they will be able to ascend the escalator slower than if it were stationary. Their relative speed to the escalator will be decreased, allowing them to maintain a steady pace upwards.


Which of these is true of a person walking up the steps of a downward-moving escalator a a constant speed?

Here are some things that are true:* The combined speed is also constant * To get the combined speed, you need to subtract one speed from the other (the speed of the escalator, and the speed of the person relative to the escalator) * Acceleration is zero
