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.
In physics, this jerk is called "acceleration". As a simplified explanation, it means that the velocity changes.
On a speed versus time graph, acceleration is represented by the line on the graph. If acceleration is constant, the line cuts through equally between the axis and starts from the zero point.
No, you have a feeling of weightlessness, but you technically aren't floating you are just falling inside the falling elevator. http://www.youtube.com/watch?v=Z42cGD1CXes
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.
distance = 1/2 acceleration x time squared; acceleration is 7 m/s/s
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.

if elevator provided with the overload protection you will get indication. if further load it starts moving and gains speed
the elevator for the hub starts to work

'v' generally refers to final velocity 'u' generally refers to initial velocity (because not everything starts from a motionless state, where 'u' would equal zero) It is better to annotate initial velocity as v0 (v-sub-zero or simply v-zero).

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.
Eagle, elevator, eyes, eyebrow and eyeglasses are things. They begin with the letter e.
