Is gravity a form of energy?

Answer 1

No. It is one of the four fundamental forces in our known universe. These four include: gravity, electro-magnetic, and strong and weak atomic forces. (More recent thoughts believe stong and weak are just different forms of the same atomic force however.)

There is a distinction between energy and force. Force (F) acting to push something a distance (d) does work (W). The so-called work function that describes this is W = Fd. Work is a form of energy. In the case of moving something (m) though work, that energy would be kinetic energy (KE = W = Fd).

Bottom line, energy is the capability to do work or cause a change. Chemical energy is expended, for example, when hydrogen and oxygen are changed into water. Kinetic energy is created when a force pushes a mass to get it moving and do work.

Force, on the other hand, is the push that uses up or creates energy. Your weight, for example, is a force. It pushes down on the thing you are sitting or standing on. Force distributed over an area is called pressure. If you suddenly lose the thing you are standing or sitting on, you'll fall and, thereby, create kinetic energy.

The force of gravity can be written as F = mg = weight; where m = the mass of the weighted object under acceleration due to gravity (g = 9.81 m/sec^2 or 32.2 ft/sec^2) on Earth's surface. But that force creates kinetic energy if the mass is dropped from some height; so that KE = W = Fd = mgd = 1/2 mv^2; where v = the velocity of the mass (m) as it falls from a height (d).

Answer 2

Gravity is the force that interacts with all the mass of the universe and they call it the weak force DUH !
Gravity is only possible when mass is available ,if there were no mass the would be no gravity .Lets take it a step further ;Mass and Gravity can only exist in NOW ,not tomorrow or yesterday, all things happen now ,gravity is only possible because of the relationship with mass acting on each other NOW ,with out now there would be nothing not even GOD .Dark energy :The perfect Vacuum of space and the initial force exerted at the big bang imparted motion to mass which has no resistance when being drawn in to a perfect Vacuum , energy can neither be created or destroyed means that the universe will expand forever because of NO resistance to its initial force created at the big bang , dark energy its simply an unrestrained explosion in a perfect vacuum .Problem solved .Dark Matter is unformed mass . The periodic table is only visible because we can feel it but just like energy in all its forms are mostly invisisble so matter can exist in an unseen state also .Problem solved .

Answer 4

Most people are misinformed about gravity. Gravity is not really an energy its the curvation of space-time. Matter bends the fabrics of space forming a curve. Imagine you filled a pool with Jello and through a balling ball. The ball will form a curve. If you throw a small ball the ball will rotate around the curvation.

The earth does the same thing it revolve around outside the curvation. If the earth is deep inside the curvation it will collide with the sun.

Answer 5

Gravity is a force but interestingly it is the weakest of all the forces and science doesnt know why...There are clues that we have more than just 3 dimensions (well 4 if you include time) where gravity may be slipping into those other dimensions causing it to "appear" weak when in fact it is jsut as strong as the other forces. Time will tell when we learn more.

As it stands science knows properties of gravity and that it exists but dont really understand what it is. Its a mystery really. It warps space/time and even tears it when dealing with blackholes. Our understanding of "everything" that is the universe will lay upon the complete understanding of gravity with quantum mechanics. There is more to gravity than just a falling apple.

Answer 6

No. Gravity is a force. It only affects energy when an object is moved in a gravity field.

Answer 7

Gravity is a force, not a form of energy. However, two things seperated by a distance d have 'potential-energy' related to the force of gravity and distance d. The force of gravity isn't constant over the whole of the distance d, it increases as they get closer. Its inversely proportional to the square of the distance between them - see wikipedia article.

For 2 large objects like planets over long distance, use

Force is proportional to g x m1 x m2 / d-squared

For small objects near the earth, the force is fairly constant. Use F = g x m

Where distance is in metres, g is the gravitational constant 9.8 metres per second per second and masses are in grams.

Answer 8

It depends what you mean, let's define our terms precisely:

Gravity is a force, not a form of energy per se.

Like any conservative force, though, it is the gradient of a potential field.

Masses moving in that potential field can gain or lose energy--gravitational potential energy.

Answer 9

No....but moving an object in a gravitational feild can cause energy to be stored or releases. Such as a diver at the top of the diving platform has more potential energy that a person at the pool level. Once he dives the petential energy is changed into kinetic energy (motion)

Answer 10

No gravity is not form of enegy , it is the force by which airth attracts a body towards it
