Gravity
One of the four fundamental interactions, gravity is responsible for the fact that any objects with mass attract one another. According to general relativity, it is a space time curvature, but according to quantum mechanics it is the result of exchanges of virtual gravitons.

Does gravity on acts on heavy objects?
Answer: Yes. Gravity affects everything. I don't know why this is even a question.
Answer: The reason something is "heavy" in the first place is because of gravity.
What does the strength of gravity depend on?
The strength of gravity depends on the value of the universal gravitational constant.
The size of the gravitational forces between two objects depends on the product
of their masses, and on the distance between their centers.
Who developed the laws of gravity and motion?
Englishman Sir Issac Newton (1643-1727) developed the three laws of motion and the theory of universal gravitation. A more accurate model for the effects of gravity, General Relativity, is sometimes used today. It was developed by the German scientist Albert Einstein in 1915/16. Most people are familiar with Newton's theory which is taught widely in high school physics.
How do you calculate specific gravity of a petroleum product?
How to calculate the specific gravity of a petroleum product involves using the ratio of the specific product density to that of water. This type of calculation is always determined at 60-degrees Fahrenheit.
Is a function of and varieties with gravity?
The function of gravity is to attract objects with mass towards each other, creating a force that pulls objects towards the center of the Earth. This force is essential in keeping the planets in orbit around the sun and maintaining the structure of the universe. Gravity plays a key role in determining the shape and behavior of celestial bodies, as well as influencing the motion of objects in space.
Does gravity decrease when driving uphill?
Technically as you go up the hill Gravity will decrease.
But the amount is too small to measure by anymethod currently available.
So in effect and for practical purposes, NO
It is not feasible for an atom to be held together by gravity because gravity is very weak at the atomic scale compared to the electromagnetic forces that bind atoms together. In theory, even if you had an atom small enough for gravity to be the dominant force, quantum effects would destabilize it.
When a large objectsvmove closer together the force of gravity becomes?
Stronger, as the gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. By moving closer together, the distance between the objects decreases, increasing the gravitational force between them.
Air does not affect gravity directly, as gravity is a force of attraction between objects with mass. However, air resistance can have an impact on the motion of objects falling through the air, as it opposes the force of gravity and can slow down the object's descent.
When leaving earth how do you overcome gravity?
To overcome gravity when leaving Earth, a spacecraft must reach a high enough speed to break free from Earth's gravitational pull. This is achieved by launching the spacecraft at a high velocity using powerful rockets. Once the spacecraft reaches escape velocity, it can overcome Earth's gravity and continue its journey into space.
How hard is gravity pulling you down?
In my case, the magnitude of the force is 195 pounds. In return, I am
also pulling the Earth up toward me with a force of 195 pounds.
specific gravity is defined as the ratio of the density of the sample/the density of water.
So the specific gravity of water is 1.
Anything more dense than water will have a specific gravity above 1 and will sink.
Anything less dense than water will have a specific gravity below 1 and will float.
What is the force of Gravity on Jupiter in Newtons?
The force of gravity on Jupiter is approximately 24.79 m/s^2, which is equivalent to about 24.79 Newtons of force for a 1-kilogram mass.
Do the center of mass and the center of gravity coincide?
Yes . If the center of pressure, for the vehicle as a whole, is not located behind the center of gravity (away from the direction of the flight path), then the vehicle will have unstable motion and can tumble. Adding fins to the rear of the vehicle (or increasing fin surface area) will move the center of pressure aft, affording stable flight. A similar effect can be produced by adding weight to the front of the vehicle.
Is Gravity is example of a centrifugal force?
No, gravity is not an example of a centrifugal force. Gravity is the force of attraction between objects with mass, while centrifugal force is the outward force experienced in a rotating reference frame.
Is there a different type of gravity underwater?
No. There's only one type of gravity, and it's the same everywhere.
How does gravity affect motion of an object?
Gravity affects the motion of an object by pulling it towards the center of the Earth. This force creates acceleration, causing objects to fall towards the ground at a rate of 9.8 m/s^2. The greater the mass of an object, the greater the gravitational force acting upon it.
Can the force of gravity on a 1 kg mass ever be more than on a 2 kg mass?
Not if they're in the same place, or simply on the same planet.
But if the 1 kg is on the Earth and the 2 kg is on the moon, then
the force of gravity on the 1 kg is 9.8 newtons (2.205 pounds), and
the force of gravity on the 2 kg is only 3.2 newtons (0.730 pound).
And if the 1 kg is on ANY planet, and the 2 kg is in space, then the force of gravity on the 1 kg is something, and the force of gravity on the 2 kg is approximately zero.
What term is defined as the measure of the force and gravity acting on the mass of a substance?
That quantity is known as the "weight" of the substance,
and it depends on how much of the substance you have.
Can gravity slow down an object?
Yes, gravity can slow down an object if it is acting in the opposite direction of the object's motion. For example, if an object is thrown upwards, gravity will work against the object, slowing it down until it eventually stops and falls back to the ground.
What are two things that determine gravity?
Mass and distance are the two main factors that determine the strength of gravity between objects. The greater the mass of an object, the stronger the gravitational pull it exerts. Additionally, the closer two objects are to each other, the stronger the gravitational force between them.
Can there be buoyancy without gravity Explain?
No, because buoyancy is the upward force exerted on an object in a fluid due to the surrounding fluid pressure being greater at the bottom of the object than the top. Gravity is necessary to create this pressure difference that leads to buoyancy. Without gravity, there wouldn't be a pressure gradient to cause the buoyant force.
Do all things have a gravity force?
Yes, all objects with mass have a gravitational force. However, the strength of the gravitational force depends on the mass of the objects and the distance between them.
What is specific gravity of caustic soda?
It depends on the solution's degree of concentration or dilution.
Is mass or weight determined by gravity?
The weight or mass of the entire matter found in the universe is determined not only by gravity but also are inluenced by the strong and weak nuclear forces that affects the atoms nucleus and its components
