Energy
Definition of energy
the ability to do work
What are the potential energies?
Electrical
Chemical
Mechanical (Gravity)
Mechanical (Elastic)
Nuclear
What are the kinetic energies?
Electrical
Radiant
Mechanical (Wind)
Thermal
Sound
Who is Albert?
Albert Einstein
The process of changing from one form of energy to another
Energy Transformation/Conversion
Elastic Energy
Energy stored by being stretched or compressed.
Mechanical Energy
The energy a body contains because of its motion which is caused by gravity or elasticity.
What did he say in ______ year?
that mass and energy can be converted into each other.
Unit energy is measured in
Joules
Gravitational Energy
Potential energy that depends on height.
Radiant Energy
The energy is caused by the movement of electromagnetic waves.
What is E=MC^2
(Energy = Mass x the speed of light squared)
Another thing that is measured in the same unit as energy.
Work
Electrical Energy
Stored electrons that aren’t moving.
Sound Energy
Energy in the form of wave motion.
Vibrations spread in all directions as one vibrating object touches another which causes that object to vibrate.
Can energy be created or destroyed? What happens if it seems to disappear?
It can only be converted from one form to another.
If energy seems to disappear, then scientists look for it which leads to new discoveries.
Give an example for all energy types
yes, potential and kinetic
(if i got this, im sry future me)
idk im not typing that all
Chemical Energy & Nuclear Energy
Energy stored in chemical substances.
The energy stored in the nucleus of an atom.
Electrical Energy & Thermal Energy
Moving electrons from one point to another in a conductor.
The total energy of atoms and molecules that are constantly in motion.
How can nuclear energy be released?
Can be released by: fusion (combining atoms nuclei) OR fission (splitting atoms nuclei)
