When riding in an elevator why does a person appear to lose weight when accelerating downward?
Weight is felt by the body resisting the pull (acceleration) of gravity. Less acceleration means less pull thus less weight. The rate at which you are accelerating downward subtracts from the pull of gravity, thus your weight is less. If you fall, say from a cliff or tall building you accelerate downward at exactly the acceleration of gravity so you're completely weightless.

When a coin is tossed in moving elevator?
When a coin is tossed in a moving elevator, its trajectory will be affected by both the acceleration of the elevator and gravity. If the elevator is moving upward, the coin will appear to fall back slightly behind the person who threw it. If the elevator is moving downward, the coin will land slightly ahead of the person who threw it.
If a cable snaps in an elevator and starts falling will the person inside float?
No, the person inside the elevator will not float. Objects in freefall experience weightlessness, but the person will still accelerate downward due to gravity. The experience will feel like weightlessness, but they are still subject to gravity's pull.
What the apparent weight if the lift moves downward with constant speed?
If you are in a lift (elevator) moving at constant speed, whether up or down, and you have no visual contact with the outside, then you don't know that the lift is moving, and no physical experiment can detect the motion. Your apparent weight is the same as when you're at 'rest'.
A 60 kg person stands on a scale in an elevator. (a) What does the scale read (in N) when the elevator is at rest N (b) What does it read when the elevator is climbing at a constant speed of 4.5 ms N?
We must use: (Force) = (Mass) x (Acceleration) Force = 400 N Acceleration = 9.8 m/(s^2) Mass = M 400 N = ( M ) x ( 9.8 m/(s^2)) After calculating, we find the mass of the man to be 40.82 kg.
Is there work done on a person ascending an elevator?
No work is done on a person ascending an elevator as the force is in the same direction as the displacement, resulting in zero work done by the force moving the person.
When a coin is tossed in moving elevator?
When a coin is tossed in a moving elevator, its trajectory will be affected by both the acceleration of the elevator and gravity. If the elevator is moving upward, the coin will appear to fall back slightly behind the person who threw it. If the elevator is moving downward, the coin will land slightly ahead of the person who threw it.
What are the two forces acting on a person as they move up and down in an elevator and when are these two forces equal and when are they not equal?
When the elevator is still the force of gravity due to your weight pressing downwards on the floor is equalled exactly by the floor pushing you upwards with the same force. When the elevator rises you feel a little heavier, and the elevator is pushing upwards with the same increased force. When the elevator descends you feel that you lose a little weight, and the floor pushes up at you with the equally reduced force, so you descend.
If a cable snaps in an elevator and starts falling will the person inside float?
No, the person inside the elevator will not float. Objects in freefall experience weightlessness, but the person will still accelerate downward due to gravity. The experience will feel like weightlessness, but they are still subject to gravity's pull.

Who is the person who made the elevator?
Elisha Otis invented the elevator in 1853.
Who is responsible if an elevator falls and you are on it?
The person who owns the building and you are in the elevator they are responsible??
What happens when you push the stop button on the elevator?
The elevator stops and a person talks to you
What is the name of the person who operates an elevator?
The person who operates an elevator is called an elevator operator. Their role involves managing the movement of the elevator, ensuring passenger safety, and assisting with loading and unloading. While elevator operators were more common in the past, many modern elevators are now automated and do not require an operator.

What is the name of a person who works in an elevator?
A person who works in an elevator is commonly referred to as an elevator operator. Their role involves manually operating the elevator, assisting passengers, and ensuring safety during the ride. While elevator operators were more common in the past, many modern elevators are now automated, reducing the need for this position.
What do you call a person working in an elevator?
Elevator man/boy. The euphemism for the job is officer of vertical transportation.
Is there work done on a person ascending an elevator?
No work is done on a person ascending an elevator as the force is in the same direction as the displacement, resulting in zero work done by the force moving the person.
