Does larger planets have more gravity than the earth?
It is more accurate to say that more massive planets have stronger gravity. If a planet had the same mass as Earth but a larger radius (i.e. it is less dense) surface gravity would be weaker, as the strength of gravity depends on both an objects mass and the distance from its center.
Do larger planets have more gravity?
Not always. The force of gravity is given by Newton's Law of Universal Gravitation: F=(Gm1m2)/r2 So if a planet had twice the mass of the earth, and the same radius, gravity would be twice as strong. However, if you had a huge planet that weighed the same as the earth (let's say it had a radius 3x greater), then gravity would be 9 times weaker at the surface. The reason big planets like Jupiter have so much gravity is becuase they have A LOT more mass than the earth does.
What happens to the mass and weight when gravity changes?
If you say, double the distance, the force of gravity is one quarter (f = 1/22 = 1/4) If you say, treble the distance, the force of gravity is one ninth (f = 1/32 = 1/9) If you say, halve the distance, the force of gravity is four times (f = 1/0.52 = 1/0.25 = 4)
Is the moon lighter or heavier then the sun?
The sun is far more massive than the moon.
Do venus have a stronger or weaker gravity?
If your question only means: "....compared to planet Earth" the simple answer is that Venus' surface force of gravity is about 90% of that on Earth. If you need the formula to compare it to the force of gravity on any given other planet, here goes: The force of gravity of gravity on Venus is a function of its mass (mVenus) on some object of let's say a constant mass mconstant. In fact the gravitational force of any planet or other mass like an asteroid is a function of its mass. For the same distance from the center of mass of a planet, the more massive it is, the stronger gravitational force based on the equation F = G (mplanet mconstant)/r2. Where G is a constant and r is the distance between the center of masses of the two objects. So look up the mass of Venus compares to the other planets and you'll have your answer.
When center of mass and center of gravity are equal?
For a uniform symmetric body in all directions the center of mass and center of gravity are the same point. Comment: I would say this happens when the force of gravity is the same at all points on a body. That means there are no variations in the gravitational field.
Does mass and weight make gravity?
The force of gravity depends on the masses involved. Weight is a force ascribed to gravity.

The force of gravity acting upon the mass of an object?
That's usually called the object's "weight". Like say if you're talking about the forces of gravity between you and the Earth, the force of gravity acting on you is your weight on the Earth, and the force of gravity acting on the Earth is the Earth's weight on you, and they're equal.
What way dose mass cores pond with weight?
The formula that relates them is: weight = mass x gravity If gravity doesn't change - which is the usual case close to Earth's gravity - you can say that weight is proportional to mass. That means that twice the mass results in twice the weight.
What does it mean to say mass and weight are porportional to each other?
That assumes gravity doesn't change. To say that two quantities, "a" and "b", are proportional means that you can write an equation: b = ka (for some constant "k"). In the case of weight: weight = mass x gravity In this case, "gravity" is the constant. That means that for different objects, the weight / mass ratio is always the same. Close to Earth's surface, this constant of proportionality - the gravity - is approximately 9.8 newton/kilogram. If you go far away from Earth, perhaps onto the surface of other planets, gravity is NOT constant, and the statement that "mass and weight are proportional" is not true.
Are you saying inertia is a source of gravity?
Gravity is related to masses. Inertia is simply another effect of masses. I would say that the mass is the source, both for gravity and for inertia. The basic unit, however, is the mass.Gravity is related to masses. Inertia is simply another effect of masses. I would say that the mass is the source, both for gravity and for inertia.

What is the vaul of the gravity on earth?
the force on say, a 1 kg mass anywhere on earths surface, is approximately 9.8 newtons, the reaction force on the earth is the same
How do solids usually behave when heated?
Their volume increases - that is to say, the solids expand. However, their mass stays the same.
Does the mass of an object change when the pull of gravity changes?
No. The mass of an object is what it's made up of, like if it's a large balloon, it's massive when it comes to air, but it doesn't weigh anything. WEIGHT is what will change. When you say "Pull of gravity" I assume you mean "gravitational pull," and the less gravity felt on an object, the less wight exerted, but the mass stays the same, because the object itself didn't change. Let's say you have a lead ball both here and on the moon. They're both led balls, but they weigh differently because of the gravity difference. Now if you added onto the moon ball so that they weigh the same, then the mass would be different but the weight will be the same. So to answer your question, no.
How does gravity impact friction?
With a fixed mass, if you say double the acceleration due to gravity, you would have to double the force to overcome friction.
How can you say that mass of a body remians uniform everywhere?
Mass is genarally of two types. Inertial Mass and Gravitational Mass. Einstein prooved both are equal. inertial mass is m= Force/acceleration gravitational mass is m= Wieght/acceleration due to gravity. How can you measure mass of apple in absence of gravity(Say somewhere in free space or imagine on any planet whose gravity is almost NIL). Remember that Mass is NOT weight. Mass is different and Weight. Weight is NOT the direct measurement of Mass. You have to devide 'weight' by the acceleration due to gravity of any place(what we call g). Free space is weightless. No balance can work there.
