So why does gravity pull you down and not push you away? Imagine someone went under the trampoline and pushed up. The ball would roll away! This would be a gravity hill, not a gravity well. As far as scientists know, matter — or stuff — always makes gravity wells and not gravity ...

The moon does this because gravity pulls it. Gravity is the pulling action of large objects such as planets and stars. Most nights, the moon is the brightest thing in the sky. This is because it reflects light from the sun. It's hot during the day on the moon. When the sun is ...
Gravity pulls everything towards its source! No matter where you are on the planet, the pull is the same. This is why “down” is always at your feet! Planet Mass & Gravity • Jupiter (the largest planet in our solar system) has way more mass than our tiny litt ...
Does that mean a black hole pulls objects around it into its center and eats them all up? No, not exactly While gravity can cause some objects to fall into the black hole, other objects will go around it in circles instead, as the earth goes around the sun...
aThe earth has gravity and the moon also has gravity.The moon has less gravity than the earth.This means that the moon's gravity does not pull as hard as the earth's gravity. 地球有重力,并且月亮也有重力。月亮比地球有较少重力。这意味着月亮的重力一样艰苦不拉扯象地球的重力。[translate]...
Does that mean a black hole pulls objects around it onto its center and eats them all up? No, not exactly. While gravity can make some objects to fall into the black hole, other objects will go around it in circles instead, as the earth goes around the sun....
If the sneakers fall back down, poof, the kinetic energy returns-- same for condensation. Thank you! I still don't know anything about this "potential energy" concept, but had been reading about it in one of the gravity threads. As a layman my first impression is that it seems to ...
However, the 3G position must be done carefully due to the effects of gravity. Gravity will want to pull the liquid metal and molten metal down, and drips by globular transfer can occur. This position requires utmost care to control the beads’ size and compensate for the effects of gravity...
