Energy and Forms of Energy, Energy Transformation
Energy transformation
A change from one form of energy to another
example of mechanical energy
A football thrown by a quarterback, riding a bicycle, or kicking a soccer ball.
electromagnetic energy
A form of energy that travels through space as waves. The energy of light and other forms of radiation.
energy
Ability to do work
Law of Conservation of Energy
Energy can't be created or destroyed, only changed
sound energy
Energy caused by an object's vibrations. Energy of vibrations carried by air, water, or other matter.
electrical energy
Energy caused by the movement of electrons. The energy of electric charges
nuclear energy
Energy stored in the nucleus of an atom
mechanical energy
The energy associated with the motion and position of everyday objects. Formula is potential energy + kinetic energy.
energy transfer
The passing or movement of one form of energy to another
examples of electromagnetic
The sunlight, microwaves, and x-rays.
thermal energy
The total energy of motion in the particles of a substance
chemical to mechanical to chemical
cow eating grass and producing milk
When you stretch a rubber band, you give it
elastic potential energy
energy transformation (steam iron)
electric energy to thermal energy
forms of energy
electric, mechanical, nuclear, thermal, electromagnetic, sound, and chemical
energy transformation (sun to plants)
electromagnetic energy to chemical energy
energy transformation (sun to plants to animal eating plants and running)
electromagnetic to chemical to mechanical
example of chemical energy
energy stored in a match, gasoline, foods you eat, or cells in your body.
two types of potential energy
gravitational and elastic
chemical to mechanical
hawk eats mouse and uses energy to fly
example of thermal energy
ice cream melting on a hot day, hot springs, campfire, or cup of hot tea.
Most common energy transformations is between
kinetic and potential energy
When potential energy increases,
kinetic energy decreases.
According to the _____________________________________________________, energy can not be destroyed or created.
law of conservation of energy
example of nuclear energy
nuclear fusion in sun, nuclear power plants use fission
electrical to thermal
plugging hot plate
When kinetic energy increases,
potential energy decreases.
In waterfalls such as Niagra Falls,
potential energy is transformed to kinetic energy.
potential energy
stored energy that results from the position or shape of an object the energy that an object has because of the position, shape, or condition of the object
energy
the ability to do work or cause change
kinetic energy
the energy of motion
elastic potential energy
the energy of stretched or compressed objects
work
the transfer of energy that occurs when a force is applied over a distance
Heat energy
thermal energy
light and heat
two forms of energy a light bulb releases
examples of sound energy
clapping, snapping fingers, singing, or anyone's voice.
Joules
SI unit for energy
chemical energy
Potential energy stored in chemical bonds
gravitational potential energy
Potential energy that depends on the height of an object
energy transformation
a change from one form of energy to another
example of electrical energy
a shock from a metal doorknob, lightning, batteries in use, or static
matter
anything that has mass and takes up space (volume)
chemical to electrical to light
battery powered laptop
energy transformation (wood burning)
chemical energy to thermal & radiant energy
