How does an escalator moves?
An escalator moves by a continuous loop of rotating steps propelled by a motor. The motor turns the gears that drive the steps in either direction, allowing passengers to move up or down effortlessly. The handrails move at the same speed as the steps to assist passengers in maintaining balance.
Which of these is true of a person walking up the steps of a downward-moving escalator a a constant speed?
The person's speed relative to the escalator is the sum of their walking speed and the speed of the escalator. If they continue moving up the steps at a constant speed, they are exerting more effort to maintain that speed compared to walking on a stationary surface. As a result, their vertical velocity relative to the ground is increased.
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.
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 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 will the person have to do if the speed of escalator suddenly increases?
Take a support .
Why is there magnets on escalators?
Magnets are used on escalators to help detect the speed and direction of movement. This information is then used to regulate the speed of the escalator for safety and efficiency purposes.
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.
What is true of a person walking up the steps of a downward moving escalator at a constant speed?
The person's speed relative to the ground is constant, however, their speed relative to the escalator is slower because they are moving against its direction.
What does a quartz watch and escalator have in common?
Both a quartz watch and an escalator use quartz crystals in their mechanism. Quartz watches use quartz crystals to regulate the timekeeping, while escalators use quartz to measure speed and movement.
How the velocity of an escalator that is going up different from the velocity of one that is going down at the same speed?
Speed is a scalar, velocity is a vector. Two objects moving at the same speed but in opposite directions will have opposite velocities. If the velocity of the elevator going up is v, the velocity of the elevator going down will be -v.
Which of thesse is true of a person walking up the steps of a downward moving escalater at a constant speed?
The person is walking faster than the escalator is moving downward in order to reach constant speed.
