Why do you feel a jerk when an elevator starts and also when it stops?

Because of something called inertia, and poor mechanics. Stuff that isn't moving likes to stay that way, and stuff that is moving likes to stay that way too. So when you force it to change, like when an elevator starts and stops, it's hard to make that completely smooth.

Why do you feel a jerk in an elevator when it starts and also when it stops its motion?
In physics, this jerk is called "acceleration". As a simplified explanation, it means that the velocity changes.
What makes you feel weightless in an elevator?
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.
Why do you feel light coming down a hill on a roller coaster?
The same thing happens if you are coming down in an elevator, or if you fall from any height. If you are standing still on the ground, you are subjected to gravity from the Earth which is effectively an acceleration of 1g or about 9.81 metres per second squared and you will feel your normal weight. If you fall from a height you will accelerate towards the ground at about 9.81 metres per second squared and you will feel "light" or indeed "weightless". On the downward hill of a rollercoaster, the rate of descent is enough to make you feel lighter than usual and similarly, on the upward hill of a rollercoaster the rate of ascent might be enough to make you feel heavier than usual. The design of the rollercoaster determines just how much lighter you will feel on the downward sections. You can try a neat little experiment if you take a set of ordinary bathroom scales with you into an elevator. You should observe that you "weigh more" when the elevator accelerates upwards and that you "weigh less" when the elevator accelerates downwards.
What happens to your weight if you are in an elevator traveling upward at a constant speed?
Your weight (the force you feel at the soles of your feet) in an elevator traveling at any constant speed in anydirection would be the same at any instant as it would be if you were in that elevator in the same place, stopped. For practical purposes, it would be the same as it would be when you're standing on the ground. Technically, weight changes with altitude, but for any existing building the difference between your weight at the lowest and highest points of the building will be so slight as to be undetectable. You'd probably lose more weight due to evaporation of moisture in perspiration and exhaled breath during the elevator ride than you would due to the slight reduction in gravity resulting from your moving a bit further from the surface of the Earth.In order for your perceived weight to change, there has to be an acceleration. Constant speed/velocity is not acceleration. You would feel a change in weight as the elevator slowed down or sped up, but you would feel your "normal" weight once the elevator reaches constant speed/velocity.

Why does it feel like you keep going when an elevator stops?
What you are feeling when an elevator stops is called deceleration. The elevator doesn't stop right away. If it did, your knees would buckle and you would fall down from the impact, so an elevator slows down like a car does just before it stops. What makes the sensation feel weird is there is no visual indication of this happening, so you may think it has stopped, but it is really just slowing down. When you get on an elevator and the doors close (hopefully), it has zero velocity. When it starts going up, it must accelerate momentarily. During this acceleration period, before the elevator reaches its constant traveling speed, your apparent weight increases. You can feel this force in your legs and feet. If the elevator suddenly stopped, you would keep going.You would continue going in an upward direction (because of your inertia), mainly because you are not buckled in or otherwise attached to the elevator. You would lose contact with the floor. During that unfortunate scenario, you would be momentarily weightless. But with nothing to propel you upward anymore, you would slow down because of the acceleration of gravity. On normally operating elevators, ones designed not to make people sick or terrify them, the deceleration is slight, so you don't lose contact with the floor. You may feel momentarily lighter (in fact, if you were standing on a bathroom scale, it would read lower during the deceleration as you approach your floor), but you would not feel weightless.
What is the elevator property?
The "elevator property" is thepsychological urge to help others that you are forced into close contact to. In other words, when you walk into an elevator full of people, you feel connected to them. If that elevator crashed, you would feel inclined to help the others out before yourself. This principle works everywhere, not just in elevators.
Why does your stomach feel as if it is falling when an elevator first?
because of the gravity
What stops people from migrating?
People will not migrate unless they feel that it is to their benefit economically. Also if they feel safe in their home country, they are less likely to migrate.
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.
What does it feel like to be bitten by a penguin?
It hurts but it also tickles. It tickles to start with but then it starts to hurt a lot.
