Kinetic energy depends on two variables..
Energy due to friction, also refred to as heat energy. example: a toaster.
The unit used for any kind of energy
Unit for mass
Unit for velocity
This type of potential energy is energy stored in chemical bonds. Plants use the suns energy to create this type of energy
Energy stored by things that stretch or compress is called potential energy
Energy used to run electronics
the total amount of potential and kinetic energy in a system
conservation of energy
the law of ...... states that although energy can change forms it cannot be created nor destroyed
Gravitational potential energy depends on two variables mass and (blank)
When two atoms combine and energy is released, occurs in the sun
When two atoms separate and energy is released.
A measure of how much input work is turned into useful output work done by the machine.
A bar free to move about a fixed point called a fulcrum
An incline plane with one or two sloping sides
Grooved wheel with a rope running along the groove
Wheel and Axle
Two wheels of different sizes that rotate together
Sloping surface used to raise objects
Incline plane wrapped around a cylindrical post
Force x distance, or equal to the change in energy
The rate of doing work, Work/time
A device that makes doing work easier
The force you exert on a machine is called the..
The force the machine exerts on an object
(Blank) energy refers to the flow of electrons
This form of kinetic energy travels in vibrations
(blank) energy includes visible light, radio waves, and even gamma rays.
This is the most used source of energy to generate our electricity.
this non renewable source of energy can be burned to generate heat for our homes or to generate electricity
This renewable source of energy uses a giant turbine to catch the kinetic energy of the air
this renewable source of energy uses solar panals to capture the energy from the sun.
Passing water through a dam to spin electric generators takes place in this renewable source of energy.
using fossil fuels to generate our electricity produces (blank) gasses in our atmosphere.
