The elevator is accelerating downwards at g / 10 or ~3.2 ft/sec/sec (.98 m/sec/sec)

note. the question shows that the weighing took place on a bathroom scale or a spring balance. If you used a beam balance or a steelyard you would always measure 100lbs.

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

When an elevator starts or stops, there is a change in acceleration which causes a shift in forces acting on your body. This sudden change can make you feel a jerk as your body adjusts to the new motion. It's similar to the sensation you feel when a car accelerates or decelerates quickly.


What happens to the reading on the scale as the elevator begins to move upward to move downward?

As the elevator begins to move upward, the reading on the scale will momentarily increase. Conversely, as the elevator starts to move downward, the reading on the scale will momentarily decrease. This change in reading is due to the acceleration experienced by the occupants of the elevator, causing a shift in apparent weight.


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 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 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.

When elevator move down with acceleration pendulum of bob what is effect on time period?

When the elevator starts moving down, the time period increases. But when the elevator is descending at a constant velocity, the time period returns to its normal.

Will a blindfolded man in an elevator know when the elevator stops or starts?

Sure. You don't even have to be blindfolded. You only have to look away from the display and lighted buttons, and you have no other way of knowing when it starts and stops, except for the feeling when you become temporarily heavy or light.


If a body starts from rest what can be said about the acceleration of body?

If a body starts from rest, it means its initial velocity is zero. In this case, if the body is in motion, it has undergone acceleration to reach that velocity. Therefore, the acceleration of the body must be non-zero, indicating a change in velocity over time.
