Remember, the force of gravity on you is pretty much constant and unchanging. However, the degree to which you 'feel' it depends on whether or not something is pushing back up at you, to balance/resist your weight. If we assume that the elevator is going at a constant speed, then we know that the net force on your body must be zero, since you are not accelerating. Therefore the elevator is still supplying an upward force to resist your weight, and you will still feel heavy. You will only feel lighter if the lift is allowed to accelerate downwards. We can justify all this with equations. If R is the force pushing up against your feet (which makes you feel heavy) then acceleration (a) = (mg - R) / m Rearranging: R = mg - ma Dividing through by mg gives an expression for the proportion of ordinary weight felt: R/mg = 1 - a/g

When you go up in an elevator, you feel heavier due to the increase in the normal force exerted by the elevator floor on your body. This increase is a result of the elevator accelerating upward, which causes your body to experience a larger force pushing against it.

Well because you are, lets round gravity up to 10m/s and if the elevator moves up at 5m/s you now weigh 50% more so if you are 100lbs you would weigh 150lbs same applies for going down if the elevator moves down at 5m/s you would weigh 50% less or 50lbs

Whenever you accelerate downward you reduce your resistance to the force of gravity.

If you don't resist the force of gravity at all ... that's weightlessness.

But you never get weightlessness on a working elevator, only a partial reduction.

The process by which a tectonic plate consisting of less heavy rock rides up over a heavier plate is known as?

The process by which a tectonic plate consisting of less heavy rock rides up over a heavier plate is known as subduction. The opposite of this process is called obduction.


What happens to an elevator during an earthquake?

During an earthquake, elevators are designed to automatically stop at the nearest floor and open the doors to let passengers out. This is a safety feature to prevent people from getting stuck in the elevator during an earthquake and to avoid potential risks such as being stranded between floors. Elevators are also equipped with seismic sensors to detect shaking and initiate the safety procedures.


Is wind erosion that picks up small particles and leaves heavier particles behind?

Yes, wind erosion can pick up small particles (such as sand) and leave behind heavier particles (such as rocks or pebbles) in a process known as deflation. This selective removal of finer particles can lead to the formation of features like sand dunes.


Where did most of the elements heavier than Hydrogen and Helium form in the Universe?

Elements heavier than hydrogen and helium primarily formed in the cores of stars through nuclear fusion processes. Elements up to iron are formed in the cores of stars, while elements heavier than iron are typically produced in supernova explosions or neutron star mergers. These heavy elements are dispersed into space during these catastrophic events, enriching the interstellar medium from which new stars and planets can form.


Why is the main reason that oceanic crust is heavier than continental crust?

Oceanic crust is denser than continental crust because it is composed mainly of basalt, which is more compact and has a higher density than the granite and other rocks that make up continental crust. Additionally, oceanic crust is thinner and therefore more concentrated, making it heavier overall.

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?

The two forces acting on a person in an elevator are gravity pulling the person down and the elevator floor pushing the person up. These forces are equal when the elevator is moving at a constant speed or when it is stationary. They are not equal when the elevator is accelerating or decelerating.

How Do we know when we are moving up and down in an elevator?

We can feel the sensation of going up or down in an elevator due to changes in our body's inertia and the acceleration or deceleration of the elevator. Additionally, visual cues such as the changing floor numbers displayed in the elevator can also indicate the direction of movement.

Why does your stomach feel as if it were falling when an elevator starts to go up?

When the elevator goes up, you experience a feeling of weightlessness due to the sudden change in velocity. This causes your stomach to feel like it's dropping or rising quickly. Your body's proprioceptive system, which helps sense motion and acceleration, is temporarily confused by the sudden change, leading to the sensation of your stomach "dropping."


What are the two forces acting on you in an elevator?

1). The force of gravity attracts you downward. 2). The floor of the elevator car exerts an upward force on the bottom of your feet. When #1 is greater than #2, you accelerate downward, and you feel lighter than normal. That happens when the car is starting to go down, or finishing going up. When #2 is greater than #1, you accelerate upward, and you feel heavier than normal. That happens when the car is starting to go up, or finishing going down. When #1 and #2 are equal, you don't accelerate at all, and your weight feels normal. That happens when the car is standing still, or rising at a steady speed, or dropping at a steady speed.
