How does energy change from potenial energy to kinetic energy?
A object falling form a height, h. At h it has graventational potential energy and when it starts to fall this energy tranferes into kenetic.ability toput mass of any sort into a motion of accelleration therefore resulting in having potential of producing kenetic energy into said mass
A ball thrown by a boy from the roof top is what motion?
When the boy is holding the ball it has Gravitational Potential Energy (GPE).When he lets go the Gravitational Potential Energy is converted to Kinetic Energy.As the ball is falling it continues to gain Kinetic Energy, however, the friction from the air on the ball increases (Air Resistance).When the Kinetic Energy and Air Resistance become equal the ball is said to have to reached Terminal Velocity.Once the ball hits the ground the Kinetic Energy is transferred to the ground through heat (Friction) and also as sound.Remember energy cannot be created or destroyed, it is always transferred.
What is potential energy and kinetic energy?
In a system the potential energy is related to forces acting between bodies inside the system. Kinetic energy of a moving body is defined as K=(1/2)*m*v^2 where m is the mass of the body and v its velocity. If no energy is transfered to or from the system then the sum of the system's kinetic and potential energy remains constant.answer2: The universe is composed or quaternions, a real number or scalar and 3 vector numbers. Energy has these two types the potential energy is the real part and kinetic energy is the vector part, for example take gravity energy:E = Pot + Kin = -mGm/r + mcV = -mu/r + mcV ,where the potential gravitational energy is the scalar part and mcV is the kinetic vector energy. V is the velocity vector.Currently Physics defines "energy as a scalar" in spite of Torque, a vector FxR with units joule or Newton -meter.Well, kinetic energy is the energy of motion and potential energy is the energy of positionPotential Energy. Stored energy that results from the position or shape of an object.Kinetic Energy Energy that an object has due to its motion.HistoryA roller coaster train going downhill represents merely a complex case as a body is descending an inclined plane. Newton's first two laws relate force and acceleration, which are key concepts in roller coaster physics. At amusement parks, Newton's laws can be applied to every ride. These rides range from 'The Swings' to The 'Hammer'. Newton was also one of the developers of calculus which is essential to analyzing falling bodies constrained on more complex paths than inclined planes. A roller coaster rider is in an gravitational field except with the Principle of Equivalence.Potential EnergyPotential energy is the same as stored energy. The "stored" energy is held within the gravitational field. When you lift a heavy object you exert energy which later will become kinetic energy when the object is dropped. A lift motor from a roller coaster exerts potential energy when lifting the train to the top of the hill. The higher the train is lifted by the motor the more potential energy is produced; thus, forming a greater amount if kinetic energy when the train is dropped. At the top of the hills the train has a huge amount of potential energy, but it has very little kinetic energy.Kinetic EnergyThe word "kinetic" is derived from the Greek word meaning to move, and the word "energy" is the ability to move. Thus, "kinetic energy" is the energy of motion --it's ability to do work. The faster the body moves the more kinetic energy is produced. The greater the mass and speed of an object the more kinetic energy there will be. As the train accelerates down the hill the potential energy is converted into kinetic energy. There is very little potential energy at the bottom of the hill, but there is a great amount of kinetic energy.TheoryWhen the train is at the top and bottom of the hill there is not any potential or kinetic energy being used at all. The train at the bottom of the first drop should have enough energy to get back up the height of the lift hill. The "Act of Faith" in riding these amazing rides which seems more of a phenomena that is only a theory. In practices, the train never could make it back up the hill because of dissipative forces. Friction and air resistance, and even possible mid-course breaks, are dissipative forces causing the theory to be changed but not destroyed. These forces make it impossible for the train to have enough energy to make it back up the lift hill's height. In the absence of the dissipative forces the potential and kinetic energies(mechanical energy) will remain the same. Since the mechanical energy is destroyed by the forces, the first hill is always the highest.KINETIC POTENTIAL ENERGY,iS the ammount of energy one has, then the other is stopped and it goes down a hill or something steep.
When the temperature of a substance decreases increases what happens?
The temperature of a substance increases as the mean random kinetic energy of its particles increases. This is because temperature of an object is directly proportional to the kinetic energy of its particles. Thus when the particles move faster as a whole, such as when the object is put near a flame, the object heats up.
What would indicate a change in molecular speed temperature or heat?
Both and one more. It is [more commonly] said that an object's temperature is a measurement of the amount of heat that it contains. Heat is in its turn a reflection of the degree of Kinetic Energy the the object holds and, finally, kinetic energy directly relates to the speed of atomic and molecular motions.
What is mechanical energy the sum of?
Energy can basically be divided in two groups: thermal and nonthermal.In principle nonthermal energy can be transformed 100 % in to any other kind ofnonthermal energy or thermal energy.For the case of thermal energy only a part of it can be transformed into a nonthermal energy through a 'Heat Engine' according to thermodynamics 2nd law.Example of a nonthermal energy is mechanical energy of which potential energy ( owed to the position of a body in a gravity field, or given to a body by a spring orsomething similar), and kinetic energy of a macroscopic body ( molecules kinetic energy in gases and liquids are not included here, they are part of the body's thermal energy) belong to it.
Which form of energy is firewood?
In ordinary usage, firewood would commonly be considered a form of potential energy, before it is lit aflame. That is, the wood is then said to possess energy that is ready to be transferred to work. Once on fire, kinetic energy is said to be released. More precisely, the wood may be said to contain chemical energy on the macroscopic level, but both potential and kinetic energy on the atomic and subatomic levels. The firewood energy is renewable form of energy. It can be renewed by growing woody plants.
What can be said about the potential energy and kinetic energy of the stone as it falls?
The longer it falls the more kinetic energy it gets while decreasing it's potential energy.
Is talking to someone face to face Kinetic energy?
It could be said that there is; kinetic energy is carried by the air in which the sound travels.The energy is carried in the sound waves
Is earth running out of energy?
Energy doesnt run out, it is just transferred. For example, a ball in a high place is said to have potential kinetic energy, if it then falls that energy is transferred to kinetic and thermal energy. Upon rest, the ball again has potential kinetic energy.
How is kinetic energy formed?
Kinetic energy is a form of energy that comes from motion. Therefore any moving object (that has a mass!) has kinetic energy. For kinetic energy to be produced, a force must act upon an object to give it an acceleration, to put it in motion. The simplest case is the conversion of potentiel energy to kinetic energy. When an object is far from its "normal" standing position (in this case the ground), it is said to have potential energy. When this object is attracted by the force of gravity, its potential energy is slowly converting into kinetic energy because the objet keeps on accelerating.
When two body collide .after collision they could move together then the colllision is?
In that case, the collision is said to be inelastic. The total kinetic energy gets reduced.
Examples of both kinetic and potential energy?
chemical and electromagnetic
Objects that are not actively moving but have the capacity to do so are said to possess?
potential energy
Does corn have kinetic energy?
No, corn could be said to have potential energy due to it's position or constituents.
How does the law of conservation of energy relate to a bow and?
I think you mean bow and arrow. In this case, when you pull back an arrow on a bow, you apply kinetic energy (the energy of motion) to the bow and arrow to give it potential energy (energy that can be turned into kinetic energy at a later time). Anyway, the laws of conservation of energy state that energy cannot be created or destroyed; therefore all energy in the world is only changed to other different forms. As I said above, your kinetic energy (coming from your body) applied action to the bow and arrow, making the kinetic energy change into potential energy. Of course, when you let go of the arrow, the potential energy changes back into kinetic energy, allowing to arrow to fly off.
What is the force that accompanies a moving part?
Friction. The #$%&#%$& who said kinetic energy was wrong.
