Why do all photoelectrons not come with the same kinetic energy?
V41238909h2j82rh
Some energy is lost in releasing the electrons from the nucleus. This energy is known as the work function, which relates to the threshold frequency. Therefore, the kinetic energy of the released photoelectron is equal to the photon energy minus the work function.

Is thermal energy the same as kinetic energy?
No, thermal is a kind of kinetic energy.
What will a car's kinetic energy be if the car's speed triples?
The Kinetic Energy Stays The Same
Can the work function depend upon the wavelength of light?
Yes, definitely . For the given metal of particular work function, decrease in wavelength of the incident beam increases the maximum value of kinetic energy with which the photoelectrons are emitted, but the photoelectric current remains the same, stoppage voltage increases.
What are the energy transformations of a slingshot?
elastic potential energy to kinetic energy
What unit is used for kinetic energy?
The same units as for any type of energy. There is no special unit for kinetic energy.
Is thermal energy the same as kinetic energy?

Is kinetic energy the same as movement energy?
Yes

An object that has linear kinetic energy must be?
Moving. Linear kinetic energy is basically the same thing as regular kinetic energy. hope that helps!
How is potential energy like kinetic?
They're not the same thing, potential energy is energy at rest whereas kinetic energy is energy in motion.
What is the same and the difference between potential and kinetic energy?
Potential is stored energy and Kinetic is just simple movement like windmills are powerd with Kinetic energy. They are both energy.
Do changes in velocity and mass have the same effect on kinetic energy?
Kinetic energy is equal to one half the mass times the square of the velocity. Thus, changes in velocity and mass do not have the same effect on kinetic energy. If you increase the mass by a factor of 10 at the same velocity, you increase the kinetic energy by a factor of 10. However, if you increase the velocity by a factor of 10 at the same mass, you increase the kinetic energy by a factor of 100.
What is kinetic to kinetic energy?
same if none has been lost. ke=0.5Xmv(squared) GPE=massxgravityxheight
If the same model plane travel 3 times faster than the same model airplane what is the kinetic energy of the faster plane?
The kinetic energy of an object varies as the square of its velocity (Kinetic energy = mv2/2). So a plane with the same mass travelling at 3 times the velocity will have 9 times the kinetic energy.
