What is required for gravity to act on every object?
For gravity to act on every object, two criteria must be met: mass and distance. Every object must have mass, which is a measure of how much matter it contains. Gravity also depends on the distance between objects, with the force decreasing as distance increases.
The size of the force of gravity depends on what?
The size of the force of gravity depends on the masses of the two objects involved and the distance between them. The force of gravity increases as the masses of the objects increase and decreases as the distance between them increases.
Is there gravity in the exosphere how much?
Since that is very near to Earth - compared to Earth's radius - the gravity will be almost the same as on the surface. If you want to know exactly how much the gravity gets reduced, look up the distance, and use the formula for gravitation.
Under what conditions gravity between two objects increase?
when the mass of either object increases, or the distance between their centers decreases. It is the attractive force that is affected by the mass of each object or the distance between them. Even though it cannot be proved from 1st principles, the attractive force relationship between the 2 objects is given by (m=mass, d=distance): m1 x m2 --------- d2 Thus, the attractive force increases when either m1 or m2 increases. This force also increases very much (as the square) when the distance decreases.
Why does the moon have lees gravity?
The force of gravity between two masses depends on the product of the masses. So if either of the masses is reduced, the force between them is reduced. The Earth has about 80 times as much mass as the moon has. So the force of gravity between the Earth and any object on it is going to be more than the force of gravity between the moon and the same object when the object is on the moon. The distance between the two objects is also involved in determining the force of gravity between them, but the above discussion of the mass is enough to answer the question.
Is the force of attraction greater or less when the distance between two objects is far?
All attractive forces, gravitational, coulombic, and magnetic vary as the square of the distance between two objects. Thus, as the distance increases, the force between them becomes much weaker and weaker.
Why is the force of gravity between you and earth greater than the force of gravity between you and a car?
The force of gravity between two objects is determined by their masses and the distance between them. The Earth has a much greater mass than a car, so the force of gravity between you and Earth is greater. Additionally, your distance from the center of the Earth is much smaller compared to your distance from a car, further contributing to the difference in gravitational force.
Is gravity canceled closer to the earth or moon?
Earth-Moon GravityThe point at which the gravity of the Earth is counterbalanced by the gravity of the Moon is much closer to the Moon. The stronger gravity of Earth has a greater effect for any given distance.Independent GravityThe Earth's gravity is greater than the Moon's, so the Moon would have a lower escape velocity and a lower possible orbit, even neglecting the fact that it has no atmosphere. Gravity diminishes with distance, so the effective gravity at any given distance from the Moon will be much less than the effective gravity at that distance from the Earth.
How much work is done by gravity on the two-block system?
The work done by gravity on the two-block system is equal to the force of gravity multiplied by the distance the blocks move in the direction of gravity.
What determines how much gravity on a planet has?
Its mass. More mass=more gravity Also the distance from the planet's center to its surface, i.e. its radius.
The ratio of the earths gravity to the suns gravity?
No meaningful comparison is possible without specifying that the distance from both bodies will be the same at the moment of measurement. If you measured the acceleration due to gravity (or your weight) some distance from the sun, and then measured the acceleration due to gravity (or your weight) at the same distance from the Earth, you would find that the measurement in the vicinity of the sun is about 332,982 times the corresponding measurement at the Earth. It doesn't matter what the distance is, as long as both are the same.
Why is there more gravity on Pluto than on Earth?
There isn't. The "surface gravity" is dependent on the mass (of the planet, etc.) and the distance of the surface from the center of mass. Pluto has MUCH LESS mass than Earth and the gravity is much less on Pluto.
