What is the source of energy as a star evolves from an interstellar cloud to the protostar stage?
The main source of energy during this stage is gravitational potential energy, as gas in the interstellar cloud collapses under gravity to form a protostar. The energy released from this gravitational collapse heats up the material and initiates the process of star formation.
Is gravitational 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 the world.
What two factors influence the gravitational potential energy of an object?
First of all, a clarification on the wording of the question: Gravitational potential energy is the energy associated with the gravitational interaction between objects with mass. Obviously if you just have a single isolated mass, it would not be under the influence of any gravitational fields and therefore there would be no gravitational potential energy. Gravitational potential energy is property that describes a whole system of masses (it could be two masses or three or four or...). When we talk about the gravitational potential energy of an object on Earth, it is implicit that we mean the gravitational potential energy associated with the system of two masses (one being the object in question, and the other being Earth).For simplicity, let's assume that we have two masses labelled m1 and m2. The gravitational potential energy (which I'll label U) is given by the relation:U = (Gm1m2)/r2where r is the distance between the centre of each mass, and G is the universal gravitational constant. You can derive this equation very simply from Newton's Universal Law of Gravitation (which you may be familiar with) and the definition of potential energy. So, what does the potential energy of this system of masses depend upon? Everything that is a variable in the equation! Namely, the mass of each object and their separation. In our everyday example of an object that is some height habove the surface of the Earth, the mass of the Earth doesn't change, and neither does its radius (distance between centre and surface). Therefore, in that particular instance, the potential energy depends only upon two things 1. the height of the object above the surface, and 2. the mass of the object.
Does the sun have either kinetic or potential energy?
The sun primarily has potential energy due to the gravitational forces that hold it together. This potential energy is released as heat and light energy through nuclear fusion reactions occurring in its core.
What type of energy is stored up?
ATP
As an interstellar gas cloud shrinks in size its gravitational potential energy?
As an interstellar gas cloud shrinks in size, it's gravitational potential energy gradually transforms into other forms of energy.
What is the source of energy as a star evolves from an interstellar cloud to the protostar stage?
The main source of energy during this stage is gravitational potential energy, as gas in the interstellar cloud collapses under gravity to form a protostar. The energy released from this gravitational collapse heats up the material and initiates the process of star formation.
Why is potential energy called gravitational potential energy?
Potential energy and gravitational potential energy are different from each other ."Potential energy is the ability of a body to do work." Anddue_to_its_height.%22">"Gravitational potential energy is the ability of a body to do work due to its height."Gravitational potential energy is a type of potential energy.
What does potential energy plus gravitational energy equals?
Gravitational-potential energy.
Is gravitational energy the same as gravitational potential energy?
It is a type of potential energy, but there are other types of potential energy, too.
Is gravitational energy kinetic?
Gravitational potential energy is a form of potential energy, not kinetic energy. It represents the energy stored in an object due to its position relative to a gravitational field. However, when that potential energy is converted into kinetic energy as the object falls, it can lead to movement and activity.
Can an objects mechanical energy be equal to its gravitational potential energy?
Yes. Mechanical energy is the sum of potential energy and kinetic energy; this includes gravitational potential energy.
Energy at a height is called what?
Energy related to the height of an object is gravitational potential energy.Energy related to the height of an object is gravitational potential energy.Energy related to the height of an object is gravitational potential energy.Energy related to the height of an object is gravitational potential energy.
Relationship between gravitational and potential energy?
Gravitational + Potential = 100 If you have 67 J of potential energy your gravitational energy would be 33 J.
Can a objects mechanical energy be equal to its gravitational potential energy?
Yes, an object's mechanical energy can be equal to its gravitational potential energy. Mechanical energy is the sum of an object's kinetic and potential energy, and gravitational potential energy is a type of potential energy determined by an object's position in a gravitational field. When the object is at rest or its kinetic energy is zero, its mechanical energy will equal its gravitational potential energy.
The energy of position such as a rock on a hill is what energy?
The energy of position in this scenario is gravitational potential energy. This energy is determined by an object's position in a gravitational field, such as the height of the rock on the hill. It represents the potential for the object to do work if it were allowed to move to a lower position.
How is gravitational potential energy different from potential energy?
It is different because gravitational potential energy is when something is getting pulled by gravity and potential energy is stored energy which means that it is not moving and the energy is not getting released as gravitational energy is.
