You weigh yourself when you are in a motionless elevator You weigh 100 lbs The elevator starts to move and you weigh 90lbs What is the acceleration of the elevator?

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?
In physics, this jerk is called "acceleration". As a simplified explanation, it means that the velocity changes.
How is speed and acceleration represented on a graph?
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.
If a cable snaps in an elevator and starts falling will the person inside float?
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
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.
What is the acceleration of a body which starts from rest and travels 87.5 m in 5 seconds?
distance = 1/2 acceleration x time squared; acceleration is 7 m/s/s
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.

What happens when you overload an elevator?
if elevator provided with the overload protection you will get indication. if further load it starts moving and gains speed
What happens after you do that maze on steam works island?
the elevator for the hub starts to work
Name something that starts at the press of a button?
tv, computer, elevator, microwave
What is u velocity when v velocity is acceleration?
'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).

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.
What starts with the latter E?
Eagle, elevator, eyes, eyebrow and eyeglasses are things. They begin with the letter e.
