Energy
Energy can change forms but is never lost
Energy changes forms.
Conversions between potential and kinetic energy
Using energy conve
Energy is always conserved
Law of conservation of energy
Energy cannot be created or destroyed, only transformed or transferred from one form to another.
Energy conversions may produce unwanted forms of energy
Energy efficiency
Energy Exists in different forms
Different forms of energy have different uses.
Energy
The ability to cause change.
Forms of energy
Mechanical
Sound
Chemical
Thermal
Heat is the transfer of energy from one body or system to another due to a difference in temperature.
Temperature is a measurement of the average kinetic energy of the atoms and molecules that make up a substance.
Electromagnetic
Light, Infrared, & Ultraviolet are all on the electromagnetic spectrum.
Light is electromagnetic radiation that can be perceived by the human eye
Some animals can see wavelengths beyond the ones that humans can.
Nuclear
Kinetic Energy and potential energy are the two types of energy
Kinetic energy
Increases as Mass and speed increase
The equation for kinetic energy is KE= (1/2)(m)(v^2)
Potential energy
The equation for gravitational potential energy is U=mgh
