Work
|
transfer of energy
|
|
|
Power
|
the rate at which energy is transferred OR the amount of energy transferred in a unit of time.
|
|
|
Kinetic Energy
|
the energy an object has due to its motion; 1/2mv squared
|
|
|
Potential Energy
|
stored energy that results from the position or shape of an object; mgh, Wh
|
|
|
Gravitational Energy
|
related to an object's height; it's equal to the work done to lift it
|
|
|
Elastic Potential Energy
|
associated with objects that can be stretched or compressed
|
|
|
Mechanical Energy
|
associated with the position and motion of an object; example: football
|
|
|
Thermal Energy
|
the total potential and kinetic energy of the particles in an object; example: lava, ice cream
|
|
|
Electrical Energy
|
the energy of electric charges; example: lightning, batteries, radios
|
|
|
Chemical Energy
|
potential energy stored in the chemical bonds that hold chemical compounds together; example: food, cells
|
|
|
Nuclear Energy
|
potential energy stored in the nucleus of an atom; example: bombs
|
|
|
Electromagnetic Energy
|
energy that travels in waves; has electrical and magnetic properties
|
|
|
Pendulum
|
At the highest point in its swing, it only has gravitational potential energy. As it swings downward, it speeds up, which it is transformed to kinetic energy. it is at its greatest speed at the bottom of its swing where all the energy is kinetic energy.
|
|
|
Juggling
|
Before it goes in the air, it has potential energy. As it moves it has kinetic energy. As it rises, it slows down. Its potential energy increases as its kinetic energy decrease. At the highest point, there's no motion and only has potential energy. As it falls, it's the opposite of rising.
|
|
|
transfer vs transform
|
transfer is when energy is moved to somewhere else and transform is when energy is not destroyed, but changed to another energy
|
|
|
Conservation of Energy
|
friction transforms mechanical energy to thermal energy; and..?
|
