F = (G m1 m2) / (r^2)
Where G is the univeral gravitational constant, m1 is the mass of the planet, m2 is the test mass, F is the force acting between the planet and the test mass, and r is the distance between the centroid of the planetary mass and the centroid of the test mass. --------------------------------------------------------------------------------------- Gravity is the force that pulls you to the ground on Earth. The strength of gravity depends on how big the planet you are standing on is (as shown by the formula above). Look in the link below to see how much you would weigh on other planets.
Io is a moon of Jupiter, not a planet. Surface gravity is about 18% of the gravity on Earth.
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.
The force of gravity of a planet is a product of its mass.
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.
Where there is mass there is gravity.
All planets have 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.
YES! The bigger or more dense the planet is, the higher the force of gravity.
