Can we stand in air?

Can we stand in air?

One answer is that atmospheric pressure doesn’t weigh down on us, it presses in from all sides, including up from under us (since there are air gaps under your shoes and feet). So standing under the atmosphere isn’t at all like standing under a 10-ton weight.

What stops you from floating in the air?

The Short Answer: Earth’s gravity is strong enough to hold onto its atmosphere and keep it from drifting into space.

Why does the Earth not move when I jump?

Even the hardest bedrock is somewhat elastic. This means that when you jump, you don’t actually exert a force on the entire earth at once. Being elastic, the entire earth does not accelerate all at once away from you when you jump. Instead, you just deform a tiny bit of earth right under your feet.

Can a plane stay still in air?

Techincally, there is only one way for the aircraft to remain hanging motionless in the air: if weight and lift cancel each other out perfectly, and at the same time thrust and drag cancel each other out too. But this is incredibly rare. To stay in the air and sustain its flight, an aircraft needs to be moving forward.

What would happen if the Earth stopped spinning suddenly?

If the Earth stopped spinning suddenly, the atmosphere would still be in motion with the Earth’s original 1100 mile per hour rotation speed at the equator. All of the land masses would be scoured clean of anything not attached to bedrock.

What time does it take to travel around the Earth?

For your entire westward trip around the Earth, the time would be between 12:00 noon and 1:00 p.m. What you are really doing is maintaining your position on the Earth relative to the sun.

What is the yearly change in the sun’s position in Sky?

The yearly change in the Sun’s position in the sky would now be just its seasonal motion up and down the sky towards the south due to the orbit of the Earth and its axial tilt.

What time would happen if a plane started flying at noon?

If you started flying at 12:00 noon, at 1:00 p.m. (according to your watch) you would cross a time zone, making it 12:00 noon again. This process would continue for as long as your plane could stay in the air: As soon as your watch passed 12:59, you’d have to turn it back to 12:00 again.
