What is the difference between kinetic energy and potential energy?
Kinetic energy is the energy in the movement.Potential energy is stored energy, ready to be used.K.E-motion energyP.E-energy stored during displacement of springs that tend to restore to original position of springKinetic energy is the energy found in every object in motion .Gravitational Potential Energy is the enegry stored in an object because of its height. For example, the energy that water has before it goes over a waterfall. Chemical potential energy is the energy that a substance can release by undergoing a chemical reaction, for example gasoline which releases energy when it is burned. Mechanical potential energy would be the kind stored in a compressed spring. Radioactive materials such as uranium have nuclear potential energy.Kinetic energy is the energy of motion.. while something is moving.. and potential energy is the energy being stored up for the object TO move.A ball rolling has kinetic energy... when you pull back a spoon to throw food at someone, when you pull back and hold it there, it has potential energy (potential to be kinetic, that is)Potential energy is the capacity for doing work that a body possesses because of itsposition or condition. While kinetic energy is energy a body possesses because it is in motion.kinetic energy is moving energy or energy used in preforming an action.potiental energy is sitting energy or energy that is being saved up.potential- when energy is stored.kinetic- when energy is movingPotential energy is stored energy, when building up to it's highest point the energy is released as kinetic energy. For example potential energy is the energy gathered when moving slowly up an amusement park ride, when you reach the top the potential energy reaches it's limit and is realeased as kinetic energy when you rocket downwards.
What is a sentence for amplified?
My headache merely amplified the child's volume.
Does sound get quieter or louder through medium?
Sound does indeed get quieter through medium. The level of loss depends on the medium that is used, and as the square of the distance from source.
What things are alternative energy sources?
Alternate Energy Sources: Solar, Wind, Hydro, Biomass, etc.There are many, but it depends a bit on what you mean by "alternate." Mostly, people mean sources other than fossil fuels (oil, coal, natural gas), and maybe nuclear fission as well. Personally I prefer the term "renewable" sources of energy because the meaning is more clear, and maybe some day in the future renewable energy sources will be our main source of power, and won't be "alternate" at all!Here are a few:Solar: Solar power or sun's energy can be used to make both electricity and fuel with solar panels. These panels take energy from sunlight and turn it into either electricity or they drive a chemical reaction to make a fuel (hydrogen gas for instance). More energy from the sun hits the earth's surface in one hour than ALL the energy used by people on the entire earth in one year!Hydroelectric: By building a dam on a river, and only letting the water pass through a small passage, you can use the force of the moving water to spin a turbine to make electricity.Geothermal: If you drill down deep enough into the surface of the earth, you will reach very hot rocks. You can inject cold water into this deep hole, and the rocks heat the water, turning it to steam. You can then use this steam to turn a turbine to make electricity.Wind: Giant windmills spin to make electricity from the force of wind moving through the blades of the windmill.Biomass: Many plants can be turned into chemical fuels that can be burned. Ethanol is the most common, and usually corn or sugar cane is grown to make ethanol. You can burn ethanol in many cars just like gasoline.Waves and Tides: The movement of water due to crashing waves or rising and falling tides can be used to spin a submerged propeller or a turbine to make electricityFusion: A costly and somewhat dangerous resource is being developed which is known as fusion. This is the same energy which generates the sun's heat and energy. It fuses hydrogen atoms into helium atoms but is not yet cost effective and they have yet to make a self sustaining reaction.Another view:Alternate renewable sources of energy are those that can be harnessed naturally and repeatedly by humans without damaging the environment or adding to the possibility of global warming.
Clerify the meaning of state the hypothesis?
Hypothesis is merely a guess at what you think is going to happen.
What is a description of energy absorption?
When energy is said to be absorbed, it is merely converted from one form to another as energy cannot be created, nor destroyed. Eg. in a traffic collision kinetic (movement) energy is converted into sound and heat energy.
How and where material are destroyed and created?
Matter cannot be created or destroyed - it can merely be rearranged or converted to/from energy.
What is the law of coservatin energy?
Energy cannot be created or destroyed but merely changed from one form to another.
How do infrared rays give heat?
Infra-red ray's do not give heat merely when they come into contact with something the infra-red (light) energy is converted into thermal energy
In condensation is energy gained or lost?
Condensation is exothermic. Energy is released during condensation. Energy can not be "lost" but merely change from one form to another.
Energy can be neither created nor destroyed?
Yes, it is stated in the law of conservation of energy. Energy, no matter what happens to it, never is created nor destroyed. It is merely converted to different forms of energy. The same applies to mass.
If energy and mass cannot be destryed than what happends to the electrons of used electrical energy and why is this used energy unable to be converted back to electrical energy?
The electrons in an electrical current are not used up by the current. They are simply moved. A simple way to think of the current is as a stream of water, except that in the current it is electrons that are flowing, not water molecules. When the energy in a water current is tapped - by a turbine, say - the water molecules are not destroyed, although the turbine obtains energy.In principle used ("converted" would be better) electrical energy could be changed back into electrical energy, except that some of it will be forever lost as heat. This energy has not been destroyed, merely converted into a form where it can do no useful work. This is an inevitable consequence of the second law of thermodynamics, which applies to all energy conversions, not just electrical ones.
What does the phrase forever and a day mean?
it means "forever" - without end. The "and a day" suffix is merely a way of emphasizing the idea of "forever".
If the mass of one photon is totally converted into energy it will yield a total energy of?
A Photon does not have any mass. It is merely a packet of energy. To calculate the energy of a photon, the formula is E = hνwhere h = Planck's constant = 6.63 x 10-34and ν = frequency of the light source (in Hz)
What type of energy is an automobile?
An automobile IS not energy; it merely USES energy.
What is another word for merely?
ânother word for merely is, happily, or joyously.
How does a pulley save energy?
A pulley does not save energy; it merely changes the direction of the force.
