An elevator can drop faster than the force of gravity. That is more than 32 feet per second squared. Push off the floor and float back down. Some express elevators from the 90th floor can scream on down safely.
The most common elevator problem in high-rise buildings is mechanical breakdowns, such as doors getting stuck or the elevator getting stuck between floors.
It hasn't really. The concept of vertical transportation remains the same as it did when it was first developed. It has only got faster and smoother.
yes because it is so cool to be a dialer Dial (802)365-482 for more info on it
can you give me one example of a weak possword
An example of a precision measurement is a reading of
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.
Yes, inside a freely-falling elevator, you would experience apparent weightlessness. This is because the elevator and everything inside it, including you, would be falling at the same rate due to gravity, creating the sensation of weightlessness.
If my weight decreases while standing on the scale in an elevator, it likely means that the elevator is accelerating downward. This decrease in weight is due to the elevator and myself accelerating at the same rate, creating a sensation of weightlessness.
Why is the elevator a good example of an inclined plane?
The earth's gravity causes objects on earth (you) to accelerate toward earth's center at approximately 9.8 m/s2, when an elevator accelerates toward the earth's center (down) some of the force that you feel from gravity (weight) is negated. This results in a feeling of weightlessness.
In a falling elevator, both the elevator and the object inside are accelerating downwards at the same rate under gravity. This creates the sensation of weightlessness, as the object is not experiencing any resistance or contact force from the elevator floor. However, gravity is still acting on the object, causing it to accelerate downwards at the same rate as the elevator.
Weightlessness is the effect that astronauts enjoy in space.
Weightlessness is the effect that astronauts enjoy in space.
The root word of weightlessness is "weight."
you are so weightlessness
The astronauts experienced weightlessness during their spacewalk.
You can be weightless when experiencing free fall, such as in an elevator dropping or skydiving, because you are in a state of apparent weightlessness due to the force of gravity acting equally on you and the objects around you, causing you to float. This sensation occurs when the acceleration from gravity counteracts the force of gravity pulling you downwards, creating a feeling of weightlessness.
