Transcript of Energy
A form of energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space.
Light is a form of electromagnetic energy
Each color of light represents a different amount of electromagnetic energy
Form of Kinetic energy
Forms of electromagnetic energy include gamma rays, X-rays, radio waves, laser light, and even microwaves!
When work is done energy is required. That energy is called mechanical energy.Mechanical energy is associated with motion and position of an object.
Examples: hitting a baseball, throwing a football,
Chemical energy is required to bond atoms together . When bonds are broken, energy is released.Chemical energy may be released during a chemical reaction.Chemical energy is a form of potential energy. Examples of chemical energy include: fuel, food, and batteries!
Magnetic Energy is the potential energy of a magnetic field
Magnetic energy can be found in door buzzers, speakers, and magnets!
The internal motion of the atoms is called
because moving particles produce heat
LAW OF CONSERVATION OF ENERGY
The Law of Conservation states that energy cannot not be destroyed or created. The law states that the total energy of a system remains constant. Energy can only be transferred from one form to another. When energy seemingly "disappears" scientists try to find out how. This has led to many important discoveries.
The nucleus of an atom is the source of nuclear energy. Nuclear energy is released in the form of heat and light when the nucleus splits.(fission) Nuclear energy can also be released when nuclei collide and join.(fusion)
Most concentrated form of energy
Used to generate electricity
Energy is the ability to do work.There are nine forms of energy. All forms of energy can be in either two of states; Kinetic or Potential. Kinetic enery is energy of motion while Potential energy is stored energy.
The electrical energy is transformed into thermal energy. The toaster heats up the toast. This is an example of thermal energy becasue the temperature is increasing and changing the state of the bread.
Friction can produce heat energy
Heat energy causes temperature changes and changes in every form of matter
Thermal energy is a form of kinetic energy
Light energy is electromagnetic energy in heat waves.
Only energy that can be seen directly
Sound energy is a form of energy associated with the vibration of matter.
Example: musical instruments
Electrical energy is the energy in electricity. Electrical currents produce electrical energy
RADIANT TO CHEMICAL
Plants use energy from the sun in the process of photosynthesis to produce glucose. The energy transformation is necessary in order to complete the photosynthesis cycle. The sun's radiant energy is formed into chemical energy in the form of glucose.
Light and Thermal
The electrical energy is then transformed into both light and thermal energy. You can see the light energy when you turn the flashlight on. You can feel the thermal energy in the ray of light that the flashlight produces.
The chemical energy stored in batteries gets transformed into electrical energy through the wires.
Flashlight Energy Transformation
A flashlight contains batteries. Chemical energy is stored in batteries.
Energy transformation of a toaster
You plug a toaster into a wall socket. The electric current moves from the wall outlet to the toaster creating electrical energy.
