How can you make a simple science model of escalator?

Look at your bicycle. As the pedal turns, the chain appearing over the rear cog wheelmoves forward and upwards over the pedal cog, returning by travelling back underneath. Exactly how an escalator works.


Is it true when a person standing on a moving escalator is relative to another person standing on the escalator?

Yes, the two people on the escalator are in motion relative to each other. However, their relative motion is different from being stationary on the same escalator, as they would perceive each other to be moving at a speed equal to the difference in their individual speeds on the escalator.


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 kind of motion do people have on a escalator?

People typically have a combination of vertical and horizontal motion on an escalator. As the escalator moves either upwards or downwards, individuals will experience a change in height as well as a forward or backward motion relative to the stationary environment.


Why do escalator handrails move at different speed to the treads?

Escalator handrails move at a slightly faster speed than the treads to ensure that the handrail is always available for passengers when they reach the top or bottom. This ensures a seamless transition for passengers getting on or off the escalator.
