Gravity is what keeps the planets orbiting round the Sun instead of disappearing off into outer space.
We feel a constant gravity force - our weight - holding us down on the Earth's surface. Isaac newton was the first one to postulate a gravity force that depends on distance. His idea was a force acting on each planet that varied with the inverse square of the planet's distance from the Sun. He was able to prove that if this was the law of gravity in the solar system, then the planets' orbits must follow Keplers' three laws.
Kepler formulated his laws from Tycho Brahe's observations of the planets' positions, but it was many years later that Newton came up with the theory that confirmed these laws. People then realised that Keplers' laws and Newton's laws of motion and the law of gravity were all part of one big theory that all stacked up, and that is what we still believe today.

How gravity affects us on different planets?
The larger the planet is, the more amount of gravity you will get. The smaller the planet is, the less amount of gravity you will get.
How does a planet's gravity vary with its mass?
The gravity of a planet is directly proportional to its mass, and inversely proportional to the square of the distance from the center of mass. For the gravity on the surface of the planet, the distance is just the planet's radius. Thus, if a planet has three times the mass, it has three times the gravity. If you are three times as far away, the gravity decreases by a factor of nine.
How does a planet gets its force of gravity?
The force of gravity of a planet is a product of its mass.
How does the gravity of planet mercury vary with its mass?
Gravity is directly proportional to mass.
Is the farther a planet is from the sun have less gravity it has?
No. The strength of gravity on a planet depends on its size and mass.
How is the mass of a planet related to the amount of gravity on a planet?
Linearily.
Can a planet suddenly lose its gravity?
No that is impossible. Gravity is related to mass, so while a planet still has mass it still has gravity.
How much gravity do the other planets have?
The amount of gravity is not really quantifiable, but the gravitational force of a planet on a standard mass at a standard distance is proportional to the planet's mass.
How is the planets size related to the pull of its gravity?
The larger the mass of the planet, the greater the force of its gravity.
What determines the pull of gravity at a planets surface?
It's mainly to do with the mass of the planet, the more mass, the higher the gravitational pull of the planet. The two are related.
How gravity affects us on different planets?
The larger the planet is, the more amount of gravity you will get. The smaller the planet is, the less amount of gravity you will get.
Is it true that the bigger the planet the stronger the gravity?
For the most part, yes. But the actual determining factor for how much gravity a planet has is based on its mass, and since size and mass are often related it is somewhat accurate to say that the bigger the planet is, the more gravity it will have.
How does the gravity of the planet vary with its mass?
The larger the planet mass, the bigger force of gravity it has.
How come earth has less gravity than other planets?
Gravity is directly related to mass. More mass, more gravity. Less mass, less gravity.
Can planet grow without gravity?
Gravity comes with mass so since a planet has mass there is some gravity. the bigger the planet the more mass it has. smaller planets have less gravity. so either way there is always some gravity on a planet.
Why there is force of gravity on your planet?
Where there is mass there is gravity.
How does a planet's gravity vary with its mass?
The gravity of a planet is directly proportional to its mass, and inversely proportional to the square of the distance from the center of mass. For the gravity on the surface of the planet, the distance is just the planet's radius. Thus, if a planet has three times the mass, it has three times the gravity. If you are three times as far away, the gravity decreases by a factor of nine.
