Before it rolls downhill, it has gravitational potential energy. As it rolls downhill, part of this potential energy is converted into kinetic energy (including rotational energy); due to friction, this will soon be converted into waste energy, mainly heat.

What happens to an object when it moves at the speed of light?
when the particle moves with the speed of light,the mass of the particle increases to infinity.... this is as per Einstein's theory of relativity....n its true.... some people say the mass decreases to zero when the particle travels with the speed of light....they are "INSANE"
What does a black objects do to light?
black object completely absorbe the incident energy and does not reflect any light because if energy incident on any other thing it reflect some portion in atmosphere that is why we can see the thing that it is in which colour but if energy absorbes by any object here total absorption no reflection
How are emissions of radiation from an atom explained by Bohrs model?
Electrons absorb energy to make electrons move from an lower energy level to a higher energy level. This energy is released as some form of e-m radiation when the electron moves from the higher level to a lower energy level.
What force transforms kinetic energy into heat energy?
Typically the force here is friction. As the object moves through some medium friction is generated between the particles of the object and the particles of the medium, converting kinetic energy into thermal energy.
What is the definition of Chemical Potential Energy?
The amount of chemical energy an object or thing *could* use. An example of this would be like a battery to your cell phone. Not all the energy is transformed to display or sound, like you want. Some energy is turned into thermal energy, which cannot be used unless its in a heater.
What happens to potential energy after it decreases?
The potential energy will have converted into some other kind of energy. For example, for an object in free fall, it converts to kinetic energy (the object moves faster); if there is some resistance, part of this energy will convert to heat.
Explain the role of friction has in the energy transformation of a person skiing downhill?
Friction and air resistance cause some of the mechanical energy of an object to change to thermal energy so the mechanical energy of the object is not destroyed. Rather, it is transformed into thermal energy. the total amount of energy always stays the same. ur welcome. you have to give me 5 bucks.
How does the gravity transform energy?
When an object is moved up, against the force of gravity, its potential energy increases. Since it requires some force to move it up, some other form of energy is converted into potential energy. When the object moves down (for example, when it falls down), this potential energy is again converted into some other type of energy. For more information, do some reading on the topic of "potential energy".
Is work and energy the same thing?
Energy, specifically heat energy, is used to do work.
What are the differences between energy transfer and energy transformation?
In an energy transfer, the energy moves from one object/material to another. In an energy transformation, one form of energy transforms into another. In both, the amount of energy does not change, but in an energy transformation, some energy is lost into the environment.
Differentiate stationary object and accelerated object?
A stationary object is a object which is not moving or which have zero kinetic energy and a accelarated object is that which is moving withs some acceleration and have some kinetic energy.
As an object falls the gravitational potential energy of the object is converted to what?
Some of its potential energy changes to kinetic energy.
Does coal have stored potential energy?
I believe the answer would be yes. All matter has stored potential energy, as this energy can be defined as the "potential" to move or perform some other action. Usually when we talk about potential energy we're talking about an object's ability to convert this energy into "kinetic energy," which is the energy an object has when it moves. Example:If a rollercoaster is at the top of a hill on the track, it has a lot of potential energy because it's going very slowly. However, when it crests the rise and begins its descent, this potential energy is gradually converted to kinetic energy as it moves faster and faster.+++Yes coal does have potential chemical energy (combustion is a chemical reaction).
What kind of energy does a waterfall exhibits?
Basically the same as any falling object. When the water is at the top, it has mainly gravitational potential energy (it will also have some kinetic, i.e. movement, energy). When it gets to the bottom, the potential energy will have been converted into kinetic energy, i.e., the water moves much faster.
What is examples of mechanical energy?
There are basically two types of mechanical energy: kinetic energy (energy of movement), which you have whenever any object moves; and potential energy (energy of position). An example of potential energy is gravitational potential energy, when an object is higher than at its lowest-possible point - it requires energy to get it there, and energy can be obtained from letting it fall down, as well as other, similar situations, where something has energy related to some force, such as elastic energy, or energy from pushing something against an electric or magnetic field.
What is energy that moves matter called?
it is due to kinetic energy that a matter moves. matter gains some velocity due to its mass on applying force on it
When you do work on an object some of your energy is to that object.?
Yes, that's basically what happens.
