# Question: What if you jump before hitting the ground?

Contents

At this crucial moment, just before it hits the ground, the elevator is falling with a certain elevator speed. 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.

## Can you jump off something before it hits the ground?

Just before the objects hits the ground, the person jumps with great force. The person lands safely on the ground after he jumps.

## What happens if you jump right before impact?

If you tried jumping just as soon as the elevator started to fall, youd actually end up falling from a greater height, and hit harder. The best time to jump is right before landing. If you jump too early, youll just crash your head into the ceiling of the elevator, and get all of your original momentum back.

## What happens if you jump off a moving object?

If you simply jump from a train moving at 10 meters per second (m/s), youll hit the ground. During impact, youll have a vertical velocity, because the train is higher than the ground. As you move down, the gravitational force will increase your vertical speed, as if you jumped off a stationary train.

## Is it possible to jump on a falling object?

Theres no way to push off an object in free fall (no normal reaction) and have no chance of counteracting the acceleration due to gravity of your body falling from a window. Before the moment of impact, you and the chair are falling at the same speed.

## Would jumping off a chair while falling?

Keeping it simple and neglecting some effects due to air resistance, both you and the chair are in free fall, so you wouldnt be able to jump off the chair. Since you are heavier than the chair, you would just send it faster to the ground.

## How far can you fall in an elevator and survive?

Betty Lou Oliver, who holds the Guinness World Record for Longest Fall Survived in an Elevator, lived through falling 75 stories (more than 1,000 feet) in an Empire State Building elevator in 1945. Had she been lying on the floor, she probably would have been killed.

## Why do elevators stop when you jump?

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. At this crucial moment, just before it hits the ground, the elevator is falling with a certain elevator speed. Because of your leap, you are falling more slowly than the elevator.

## Is it possible to double jump IRL?

Spoiler alert: double jumping like Mario in Super Smash Bros. isnt really possible. Its true that there is some force you could apply to the air beneath you in order to push off of it, but we lack the musculature to do so. Otherwise, humans could fly.

## Can you survive falling off a building with a chair?

Therefore, jumping off the chair will probably still hurt you just as much as crunching to the ground. As an addendum, a more likely way the chair could save you, is if the legs were extremely long and buckled over a large enough period of time to lower the average force enough such that it wasnt enough to kill you.

## Can jumping break an elevator?

Jumping in an elevator can sound fun, but it is often not worth the effort. Individuals may find that they can hop around with no ill effects, which may result in damages under the surface of your system. In some instances, causing a large jolt can cause your elevator cab to halt, necessitating rescue measures.
