Why do you weigh less going down an elevator?
Once the elevator moves down at a constant speed, everything is normal once again. The support force is equal to the weight only if the acceleration is zero. If the acceleration is negative (elevator going downward), the support force is less than the weight.
How many floors can you fall in an elevator and still survive?
Betty Lou Oliver holds the Guinness World Record for the longest fall survived in an elevator, falling 75 stories in the Empire State Building in 1945.
What happens to your body in an elevator?
You Could Be Lacerated If Enough Debris Collects On The Elevator Floor. Even if you lay on your back, equally distributing body weight in a crashing elevator, you could still be harmed. The crashing cabin may fill with broken parts and debris during the fall.
Why do you feel heavy in an elevator?
If you stand on a scale in an elevator accelerating upward, you feel heavier because the elevator’s floor presses harder on your feet, and the scale will show a higher reading than when the elevator is at rest. The force exerted by the scale is known as apparent weight; it does not change with constant speed.
Does gravity change in an elevator?
When the elevator is moving, we will weigh our normal weight. Since we are already moving at the same speed as the elevator (up or down), nothing is affecting us to change our weight. So for a short time, we are pushed into the floor more and our weight goes up. The same thing works when the elevator starts moving.
Why can’t you jump in a falling elevator?
When the floor of the elevator makes a sudden stop due to hitting the base of the lift shaft, you too will make a sudden stop. Because of your leap, you are falling more slowly than the elevator. The speed at which you hit the floor of the (suddenly stopped) elevator is the elevator speed minus your jump speed.
