# What is earths gravity in gravitational potential energy?

The Earth's gravitational field and gravitational potential energy are really two quite different things. The relationalship is the following:

Gravitational potential energy = mass x gravity x height

Where gravity is the acceleration due to gravity - near Earth's surface, that's 9.8 meters/second2 - or the equivalent, weight per unit mass (which near Earth's surface is 9.8 newton/kilogram).

### What is the equation for caculating an object's potential energy?

That depends what kind of "potential energy" you are talking about, but without further specification, this usually refers to gravitational potential energy. The formula for gravitational potential energy is PE = mgh, that is, mass x gravity x height. If mass is in kg. and gravity in meters per second square (use the value 9.82 for Earth's gravity), and height in meters, then the energy will be in Joule.

### If there is no gravity Does potential energy of objects still exit Mechanical energy is produced by force. Gravity is a special force which is unlimited.Potential energy of objects is unlimited.?

If you leave earths gravitational field (sufficiently), objects will have a very negligible gravitational potential energy. You can consider it zero. But what if it were a compressed spring that you brought out into 'deep space'? It would still retain elastic potential energy. A bomb in deep space would still have explosive(?) potential energy. With that said, if you had two or more objects in deep space, they would have gravitational potential energy between the…

### How can the gravitational potential energy of an object be changed?

Gravitational potential energy is equal to mass x gravity x height. Changing either the mass or the height will work. Gravitational potential energy is equal to mass x gravity x height. Changing either the mass or the height will work. Gravitational potential energy is equal to mass x gravity x height. Changing either the mass or the height will work. Gravitational potential energy is equal to mass x gravity x height. Changing either the mass…

### Does speed affect gravitational potential energy of an object?

Does speed 'effect' the gravitational potential energy of an object? No, but gravitational potential energy can be converted into kinetic energy - so the gravitational potential energy can effect the speed. Ep = mgh Energy Potential = mass * 9.81 (gravity) * height Speed / Velocity is absent from that equation.

### Why is gravitational potential energy renewable?

It is renewable because you can always raise an object or raise yourself and gain gravitational potential energy. You cannot run out of gravitational potential energy and even now you have some of the the energy because gravity is always pulling you. It is just a matter of how much gravitational potential energy you have. Go on the top Mt. Everest and you will have more gravitational potential energy than most of the people in…

### Will gravitational energy have more or less energy if its dropped higher?

Gravitational energy basically refers to gravitational potential energy. The formula is: GPE = mgh (i.e., mass x gravity x height) In other words at a higher position, an object has more gravitational potential energy. Please note that once an object is dropped, it no longer has such gravitational potential energy. The potential energy is converted to kinetic (movement) energy; which of course will be greater if the initial potential energy was greater.

### How do you find the gravitational potential energy if you have the weight in newtons and the acceleration and the height?

The gravitational potential energy is the product of (mass) x (acceleration due to gravity) x height). The first two terms ... (mass) x (acceleration due to gravity) ... are the object's weight. So if you already know its weight, then the gravitational potential energy is just (weight) x (height) and you don't need to use gravity at all.

### How can you increase potential energy?

Potential energy is vague, which consists of gravitational potential energy, chemical potential energy , etc. How to increase Gravtiational potential energy? Gravitational energy = mass x gravity constant x height looking at the equation, by increasing the height or increasing the mass. Chemical potential energy is basically stored energy, increasing the mass of the stored energy.
