Why does the Earth not move when you 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.

Why do we come back down when we jump?

The Earth’s gravity is a force that works kind of like a magnet. When you jump in the air, you come back down because gravity is pulling you towards the center of the Earth. Gravity does a lot more than just keep your feet on the ground. The Sun also has a gravitational (grav-uh-TAY-shun-ull) pull.

Does the Earth accelerate?

Yes, the Earth does accelerate/decelerate during its path around the sun. In fact, any moving object that is not traveling in a straight line has to accelerate/decelerate, for acceleration is a change in velocity over time and that is a vector that has both directional and magnitude components.

Why don’t we fall from the Earth?

A force called gravity is pulling you down towards the centre of the Earth. Anything with mass also has gravity, the more mass something has, the stronger the pull of gravity. So we don’t fall off the Earth at the South Pole because gravity is pulling us down towards the centre of the Earth.

How fast does the ground move when you jump up?

On the surface of the Earth, say at the equator, the ground is moving at about 1000 MPH. But so are you. When you jump up and are no longer in contact with the surface of the Earth, this fact does not change. You still have a speed of 1000 MPH in the eastward direction.

What happens to your velocity when you hover above the ground?

You are coupled to the reference frame of the Earth. While on the surface, your velocity relative to the Earth is zero. If you start to levitate above the ground, you are still attached to the reference frame of the Earth and will hover over the same spot on the ground.

Why does The Merry-Go-Round rotate faster than the Earth?

The reason is that a merry-go-round is rotating more times per hour than the Earth is. So in comparing the two, Earth rotates slowly, the merry-go-round rotates much much much faster, and it’s this rotation speed that is the big factor.

Why do we get less rotation when we jump higher?

A rotating mass influent on the gravitational potential. This potential is twisted through the rotating body. And because this body is not alone in the space other masses influent too. Than higher you jump than more you “feel” the other masses and you will get less rotated.
