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.
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 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.
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 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 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.
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.
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 happens when speed increases?
when speed increases, velocity changes.
When the speed of particles in a gas increases what els increases?
As the speed of the particles in gas increases the heat of gas increases as well.
What does the lifting force on an airplane wing do?
increases with speed
