Gravitation, or gravity, is a natural phenomenon by which physical bodies attract with a force proportional to their mass. In everyday life, gravitation is most familiar as the agent that gives weight to objects with mass and causes them to fall to the ground when dropped. Gravitation causes dispersed matter to coalesce, and coalesced matter to remain intact, thus accounting for the existence of the Earth, the Sun, and most of the macroscopic objects in the universe. Gravitation is responsible for keeping the Earth and the other planets in their orbits around the Sun; for keeping the Moon in its orbit around the Earth; for the formation of tides; for natural convection, by which fluid flow occurs under the influence of a density gradient and gravity; for heating the interiors of forming stars and planets to very high temperatures; and for various other phenomena observed on Earth.
Gravitation is one of the four fundamental interactions of nature, along with electromagnetism, and the nuclear strong force and weak force. Modern physics describes gravitation using the general theory of relativity by Einstein, in which it is a consequence of the curvature ofspacetime governing the motion of inertial objects. The simpler Newton's law of universal gravitation provides an accurate approximation for most physical situations.
What else can I help you with?
How does gravitational force acting on the planet compare to the gravitational force acting on the moon due to the planet?
The gravitational force acting on the planet is much greater than the gravitational force acting on the moon due to the planet. This is because the planet has a significantly larger mass than the moon, resulting in a stronger gravitational pull on the moon towards the planet.
What planet would you have more force to take of?
It would be more feasible to take off from a planet with less gravitational force, such as Mercury or Mars, compared to a planet with stronger gravitational force like Jupiter or Saturn.
How does weight change on earth and other planets?
Weight on Earth is determined by the gravitational force between an object and the Earth. The weight of an object would be different on other planets because each planet has a different gravitational pull. Weight can change depending on the strength of the gravitational force, which varies based on the mass and size of the planet.
How does the gravity of the planet vary with the planets mass?
The gravitational force on an object at a standard distance is proportional to the mass of the planet.
How does the planets mass vary with the gravity of the planet?
The gravitational force on an object at a standard distance is proportional to the mass of the planet.
Which planet would have the greatest gravitational force?
The planet that has the greatest gravitational force is Jupiter.
How does gravitational force acting on the planet compare to the gravitational force acting on the moon due to the planet?
The gravitational force acting on the planet is much greater than the gravitational force acting on the moon due to the planet. This is because the planet has a significantly larger mass than the moon, resulting in a stronger gravitational pull on the moon towards the planet.
Does weight change as gravitational force changes?
Weight is a measure of the force of gravity acting on an object, so as the gravitational force changes (for example, by moving to a location with different gravity), the weight of an object will also change. A person will weigh less on a planet with weaker gravitational force compared to a planet with stronger gravitational force.
Why is your weight different in other planet than in earth?
When you are on a planet your weight depends on how massive the planet is and how close to the center you are (planet's radius). That's because the planet is attracting you with the force of gravity and the force is larger if its mass is larger and the distance to the center is smaller. Since the different planets have different masses and different sizes the gravitational force on you will be different, so your weight will be different.
Which planet has the biggest gravitational force?
Jupiter.
How and why weight or gravity changes on planet earth?
the gravitational power of the planets are different.weight of any substance depend on both gravitational and magnitude(mass).since mass dose not change any planet but gravitational force change so weight is different at different planet. W=m multiply g
The gravitational force of the planet pulling on the sun is?
It is EXACTLY the same as the force of the sun pulling on the planet.
What planet would you have more force to take of?
It would be more feasible to take off from a planet with less gravitational force, such as Mercury or Mars, compared to a planet with stronger gravitational force like Jupiter or Saturn.
Which force is responsibel for revolving the planet around the sun?
gravitational force
How could one decrease the gravitational force between a planet and an object orbiting the planet?
Gravitational force depends only on the masses involved, and on the distance. Thus, to DECREASE the gravitational force, you would have to reduce the mass of the planet or the object (take some stuff away from it); or increase the distance.
What affects the shape of the planet's orbit?
The size of the planet along with the gravitational force within the planet.
How is the gravitational force on Mars different from that of Earthwhat causes the difference in the gravititional force?
The gravitational force on Mars (per unit mass) is less than the corresponding gravitational force on Earth. The strength of this so-called "gravitational field" depends on a planet's mass and its diameter: more mass --> more force; greater diameter (at the same mass) --> less force. You might also say that it depends on the planet's average density and its diameter. In this case, more density --> more force; greater diameter (at the same density) --> MORE force.
