All planets have gravity.
Yes, gravity does depend on the planet you are on. The force of gravity is determined by the mass of the planet and your distance from its center. Therefore, gravity will be different on each planet based on these factors.
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.
The gravity on Mars or any other planet pulls you toward the planet's center.
No Mercury, either the metal or the planet is not equal to gravity. Gravity is a force of nature, not a planet or a substance.
The larger the planet mass, the bigger force of gravity it has.
Mercury, because it's the smallest if you don't consider Pluto to be a planet.
Where there is mass there is gravity.
Gravity depends largely on mass, the bigger the planet the greater the gravity should be
Jupiter has the strongest gravity. The bigger the planet, the stronger the gravity. The moon is kind of small, so it's gravity is weaker.
No. The strength of gravity on a planet depends on its size and mass.
No that is impossible. Gravity is related to mass, so while a planet still has mass it still has gravity.
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.
