The heavier you are, the steeper the sides of the trampoline well. That is why really massive things in the universe – like the Sun or black holes – have stronger gravity than Earth. So why does gravity pull you down and not push you away? Imagine someone went under the trampoline and...
Gravity is a force that attracts two objects. Many people think of Sir Isaac Newton and how he watched an apple fall from a tree when we think of gravity. Gravity does not just relate to falling objects, but is also a force that pulls and keeps objects where they belong....
Here's why the force of gravity pulls us down rather than up. The answer involves Einstein and the bendy realm of space-time.
A physics student might encounter gravity in physics in two different ways: as the acceleration due to gravity on Earth or other celestial bodies, or as the force of attraction between any two objects in the universe. Indeed gravity is one of the most fundamental forces in nature. Sir Isaac ...

In the 1960s, humans set out to discover what the red planet has to teach us. Now, NASA is hoping to land the first humans on Mars by the 2030s.
on the line. and we just have a controller that's dialing in that torque to give you a fixed tension and that fixed tension cancels out the difference in gravity between earth and mars. engineers also had to make sure that ingenuity was stable enough to take off and land without falling...
Since the Moon is not only influenced by Earth's gravity, but also the gravitational pull of the Sun and the other planets in the solar system, each orbit around Earth is slightly different from the last. As a result, the Moon's orbital ellipse changes, month by month...
Galaxies are complex systems held together by gravity. They're made up of gases, stellar dust and millions — sometimes even billions — of stars, which are accompanied by their own planets and asteroid belts. Out of the more than 200 billion galaxies, many have a spiral shape (like the ...
