When an electron absorbs a photon of light, it gains energy. This is quantized. When an electron gains energy, it moves to a higher energy level. Thus giving the equation hf=mcv. Therefore, as more energy is given to the electron, it gets 'excited' and maintains the energy by moving to a higher energy leve.

∙ 11y agoThe Law of conservation of energy holds when a photon of light emits from the excited atom, becuase the energy absorbed by the atom during its excitation is exactly balanced by the energy emitted during its de-excitation.

∙ 8y agoYes, it can get lost. TOTAL energy is conserved (i.e., it can't get lost); though (according to the Second Law of Thermodynamics), USEFUL energy can and will decrease over time.

What will be the kinetic energy of an arrow having a potential energy of 50J after its shot from a bow?
Assuming no energy is lost, the 70 J of potential energy will be converted into 70 J of kinetic energy.Assuming no energy is lost, the 70 J of potential energy will be converted into 70 J of kinetic energy.Assuming no energy is lost, the 70 J of potential energy will be converted into 70 J of kinetic energy.Assuming no energy is lost, the 70 J of potential energy will be converted into 70 J of kinetic energy.
What is kinetic to kinetic energy?
same if none has been lost. ke=0.5Xmv(squared) GPE=massxgravityxheight
Why velocity of a mass attached to a spring is maximum at mean positions and zero at extreme positions?
This can easily be understood with conservation of energy. Assuming that no energy is lost, potential energy is continuously converted to kinetic energy, and vice versa. At the mean position, the potential energy is zero, therefore the kinetic energy (and hence the velocity) is at maximum.This can easily be understood with conservation of energy.

Why do people think objects have lost energy when they slow down also state in what form of energy is lost?
The object will have lost kinetic energy. This energy has probably gone as heat due to friction.
What is the momentum of marbles after collision?
Same as before the collision. This applies whether the collision was elastic (no loss of kinetic energy) or inelastic (some kinetic energy lost).

When potential energy is converted to kinetic energy can it be reversible?
Kinetic energy can be reconverted into potantial energy, but not with 100% efficiency. Some energe is lost in the process.
When a moving object hits another can energy be lost?
No energy is lost in such a collision, although kinetic energy is converted into thermal and possibly into potential energy.

Potential energy is released whenever an object what?
- goes into motion. This energy is transformed into kinetic energy. Kinetic energy is changed into heat by the friction process and is finally lost through dissipation.
What is the Lost kinetic energy in an impact?
Heat, noise, stress in materials...
What happens to gravitational potential energy as a roller coaster moves down hill?
Yes. As the car goes down the hill, the potential energy decreases and the kinetic energy increases. However, not all of the potential energy becomes kinetic energy. Some of it is lost to heat and sound energy.
Is kinetic energy easily lost?
Kinetic Energy - this is the energy which came from the different radiation . the best example is MAGNET there is a popular energy that can attract to other materials and different metalic objects From: JayRica

What is a by product of friction?
As a result of friction, kinetic energy is commonly lost; the result is heat energy.
