Gravity formula

Gravity is a force that pulls things towards each other. Imagine you have a big magnet and a small toy car. If you bring the magnet close to the car, it will start to move towards the magnet. This is because the magnet is attracting the car, just like how the earth attracts everything around it.

Scientists have discovered that the strength of gravity depends on two things: the mass of the objects involved and the distance between them. Mass is how much matter (or stuff) an object is made up of. So, the bigger and heavier something is, the more it will pull on other things with its gravity.

The formula to calculate the strength of gravity is called the "universal law of gravitation" and looks like this:

F = G x ((m1 x m2)/r^2)

Don't worry if it looks scary! F stands for the force of gravity, which is how strong the attraction between two objects is. G is a constant number that scientists use to make the formula work. m1 and m2 are the masses of the two objects you're interested in, and r is the distance between them.

So, if you have two planets with different masses and they are a certain distance away from each other, you can use this formula to figure out how strong the force of gravity will be between them. This formula helps scientists understand how everything in space moves and interacts with each other, from planets to galaxies.
