Energy Flashcards
List the six forms of energy besides Potential and Kinetic Energy
- Mechanical Energy
- Thermal Energy
- Electrical Energy
- Chemical Energy
- Nuclear Energy
- Electromagnetic Energy
What is Mechanical Energy?
How do you find the mechanical energy of an object?
Mechanical Energy is the form of energy associated with the position and motion of an object. Sound is a form of mechanical energy.
Mechanical Energy = PE + KE
Examples: Waving, A kit flying in the air, a ball rolling (basically any movement that occurs)
What is thermal energy?
Thermal Energy is the energy of the moving particles (atoms {Matter is made up of atoms] or molecules) in an object or substance.
***Atoms and molecules are ALWAYS moving
More KE of atoms and molecules = more thermal energy (molecular movement) and vice versa
Examples: The sun, fire, hot cocoa, EVERYTHING!!!!
What is temperature actually a measurement of?
Temperature is actually a measurement of the kinetic energy of atoms and molecules.
***All matter has thermal energy because the atoms and molecules are always moving.
What is electrical energy?
Electrical energy is the energy of moving electrons (like when you get a shock touching a doorknob)
Examples: Lightning, radios, ***batteries- they produce energy, so they could work for chemical energy, anything you plug in
What is chemical energy?
Chemical energy is the energy that is used to bond atoms together or that is released when compounds break apart. ***This is potential energy-it is stored for later use.
Examples: match, battery, food, fuel
What is nuclear energy?
Nuclear energy is the energy that is the result of nucei of atoms splitting apart (fission) or joining together (fusion)
Examples: Nuclear energy or bombs, sun, MRI’s
What is electromagnetic energy?
Electromagnetic energy is the energy of light and other forms of radiation.
Examples: light, microwaves, x-rays, UV radiation
What does the law of conservation of energy state?
The law of conversation of energy states that energy is neither created nor destroyed. It converts into other forms.
What is energy?
Energy is the ability to do work or cause change.
What is work?
Work is when a force causes an object to move.
***If an object doesn’t move, then work was not done.
When work is done, energy is transferred from the object applying the force to the new object.
Simply: work is a transfer of energy.
What are the 2 types of energy?
The 2 types of energy are potential energy and kinetic energy.
What is potential energy?
Potential Energy is stored energy. It is the energy an object has because of it’s position or shape.
An object with potential energy has the potential to do work but may not be doing work right now.
What is gravitational potential energy?
It is the potential energy due to gravity.
the higher something is off the ground, the more GPE it has.
What is the formula of GPE?
GPE = weight x height
