Why does gravitational force predominate over electric force for astronomical bodies?
Gravitational force predominates over electric force for astronomical bodies because gravity is a long-range force that acts on all masses, while electric force is a short-range force that is much stronger at small distances but rapidly decreases with distance. In astronomical scales, the masses involved are much larger and the distances much greater, making gravity the dominant force. Additionally, astronomical bodies are typically electrically neutral overall, so electric forces between them are relatively weak compared to gravitational forces.
Does gravity effect celestial bodies?
Yes, gravity affects celestial bodies such as planets, stars, and moons. Gravity is the force that causes objects with mass to be attracted to each other, keeping planets in orbit around stars and moons in orbit around planets. The strength of gravity between celestial bodies is determined by their masses and distances from each other.
If gravity is same for all bodies why not on moon and earth?
The gravitational constant is the same for all bodies.The actual force depends on the masses of the bodies (and the distance between them).Since the mass of the Moon is considerably less than the mass of the Earth, the Moon's surface gravity is lower than the Earth's surface gravity.
What two celestial bodies does gravity come from?
There is a pair of gravitational forces between every two masses in Creation. The two that influence the Earth the most are the Sun and the Moon. But the forces of gravity are also significant between Earth and Venus, and between Earth and Mars.
Which factor determines the strength of gravity between earth and the sun?
The same factors that determine the force of gravity between ANY objects. (1) The masses involved, (2) the distance between the masses.
Explain how the law of gravitation enables us to measure the masses of astronomical bodies?
You can use Newton's law of universal gravitation. The law states that F = (G*m^2)/(r^2) where F is the force in newtons (N), m is the mass in kilograms (kg), r is the radius in meters (m)

Who said The force of gravity between two bodies is directly proportional to the product of their two masses?
Avogadro
What is the force of attraction between bodies in the universe?
The force of attraction between bodies in the universe is primarily governed by gravity. Gravity is a universal force that attracts all objects with mass toward each other. The strength of this gravitational attraction depends on the masses of the bodies and the distance between them.
Are hydrogen ions affected by gravity?
as we know gravititational force is directly proprotional masses of bodies. That means yes they are
Is an equal-arm balance used to measure mass?
in a gravity field it can find 2 equal masses
Is it true that thje force between any two bodies is inversely proportional to their masses?
No, the force between two bodies is not always inversely proportional to their masses. The force of gravity between two objects is actually directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
What has the impact been on gravity?
Gravity is only affected by masses, and by how far you are from those masses.
What is gravity definition?
Gravity is the force of attraction between objects that is due to their masses.
What is measure of the pull of gravity on an object?
The simplest answer is quite obviously mass, the heavier an object, the greater the pull of gravity. In fact in physics terminology, weight means the force by which you will be attracted towards the center of the earth. Also Newton's Law of universal gravitation states that the pull of gravity equal the product of the masses of the two bodies involved divided by the square of the distance by which they are apart.
What does gravity do to two masses?
Gravity causes two masses to attract each other, pulling them together with a force that is proportional to the product of the masses and inversely proportional to the square of the distance between them. This gravitational force is responsible for keeping celestial bodies in orbit around each other and determining the trajectories of objects in space.
What did Newton say about how the distance between two bodies affects gravity?
Newton said that the gravitational attraction between two objects is directly proportional to the product of the two masses and inversely proportional to distance squared. Gravitational attraction between masses A and B = constant x mass A x mass B / distance2
