Energy can neither be created nor destroyed. It is converted to other forms of energy.
There is potential energy and kinetic energy. Sitting on your bicycle on top of the hill you have no kinetic energy, only potential energy.
When you ride down the hill, the potential energy is used up (you go down the hill) and it converts to kinetic energy (speed).
"What happens when you stop at the bottom of the hill - wasn't the potential and kinetic energy destroyed?" No. All the potential energy was converted to kinetic energy. The kinetic energy was converted to heat through the wind resistance. So, if you had an extremely accurate thermometer, you would see the air and bicycle temperature rise as you went down the hill.

Is a joule a unit of measure of all forms of energy?
Yes, any type of energy can be expressed in joules. In practice, other energy units are sometimes used, for example calories for heat energy and food energy (this is gradually being replaced by the joule), and eV (electron-volt) for the energy of subatomic particles. But it is always possible to express such energies in joules.
A bullet traveling upwards has what type of energy?
it has both potential and kinetic energies as when it is going upwards, the potential energy increases while the kinetic energy decreases until it reaches the top, and then the kinetic energy is zero and the potential energy is maximum.
Does momentum conserved during collisions?
Energy, if collision is rigid, total momentum is a constant also.
What type of energy is lost energy on energy?
energy can not be lost it can only be transported into other things
What are the units for gravitational potential energy?
You use the same units as for any other type of energy.You use the same units as for any other type of energy.You use the same units as for any other type of energy.You use the same units as for any other type of energy.

How is sound energy and light energy alike?
firstly both are type of energies. secondly, both energies can be used to obtain heat energies. thirdly both can be detected by human senses.

What type of energy is produced in your body?
Technically, your body does not make any energy. Your body converts one form of energy, mainly chemical, to various other from of energies.
What type of energy causes electrons to jump?
Electrical energy ; ) and potential, kinetic, magnetic, or heat energies
Which type of energy refers to the sum of potential and kinetic energies in the particles substance?
Thermal energy A+++
What type of energy releases energy?
as far as i know energies don't release energies. they transfer their form from one to another. energy can neither be created nor destroyed, it only changed it's form.
X-rays are what type of energy?
Electromagnetic Radiation; photons with exceptionally high energies.
What is an alternate source of energy?
That usually refers to any energy type other than the ones that are commonly used. Usually there is great overlap between "alternative energies" and "sustainable energies" also known as "renewable energies".
What is meant by conventional energy resources?
The energies which can be used again and again. this type of energy is called non conventional energy. This is otherwise called as renewable energy.
