Does force depend on height?

Does force depend on height?

The change in velocity is very small, and the change in time is small. When you hit the ground falling from 50 meters, the change in velocity is very large, and the change in time is small. This means the hitting force goes up, or is proportional to the initial height. Bigger fall, results in a bigger force.

Is gravity stronger the higher you go?

In addition, gravity is weaker at the equator due to centrifugal forces produced by the planet’s rotation. It’s also weaker at higher altitudes, further from Earth’s centre, such as at the summit of Mount Everest.

Does gravity affect taller people more?

The gravitational effect is probably too small to dominate over other factors such as genetics and nutritional effects. Astronauts experiencing microgravity in space have indeed been found to return to Earth a few centimeters taller than when they left.

Does lying in bed make you taller?

There is less gravity pushing down on the vertebrae, so they can stretch out – up to 7.6 centimeters (3 inches). To some degree, a similar stretching of the spine happens to you every night. When you lie down, gravity isn’t pushing down on your vertebrae. You will find that you’re about a centimeter or two taller.

At what height does the gravitational force end?

Near the surface of the Earth (sea level), gravity decreases with height such that linear extrapolation would give zero gravity at a height of one half of the Earth’s radius – (9.8 m·sˆ’2 per 3,200 km.)

Does being in space make you taller?

Astronauts in space can grow up to 3 percent taller during the time spent living in microgravity, NASA scientists say. That means that a 6-foot-tall (1.8 meters) person could gain as many as 2 inches (5 centimeters) while in orbit. Once the astronauts return to Earth, their height returns to normal after a few months.

Are any astronauts lost in space?

Cosmonauts Georgi Dobrovolski (left), Vladislav Volkov (middle), and Viktor Patsayev (right), the only three people to die in space, are featured on three USSR stamps. On June 29, the cosmonauts loaded back into the Soyuz 11 spacecraft and began their descent to Earth. And that’s when tragedy struck.

Would a body decompose in space?

If you do die in space, your body will not decompose in the normal way, since there is no oxygen. If you were near a source of heat, your body would mummify; if you were not, it would freeze. If your body was sealed in a space suit, it would decompose, but only for as long as the oxygen lasted.

What would happen if you were lost in space?

If you’re on a functioning spaceship, with a way to grow and cycle all those supplies, you’ll probably end up running into something like radiation or an asteroid that will rock your world. Otherwise you’ll die of old age. Your skin would also severely burn from the uninhibited radiation permeating space.
