Energy and work Flashcards
A unit used to measure energy and work. One calorie is an equal to 4.18 joules of energy; one joule of work is done when a force of one Newton moves an object one meter.
Joule
Stored energy; the energy an object has due to its position, molecular arrangement, or chemical composition.
Potential energy
The energy of motion. A moving object has the most kinetic energy at the point where it moves the fastest.
Kinetic energy
A combination of the kinetic energy and potential energy an object has.
Mechanical energy
A law stating that no matter how energy is transferred or transformed, all of the energy is still present in one form or another.
Conservation of energy
The rate at which works done.
Power
The unit of measurement for power, which is equal to one joule of work done or energy transferred in one second.
Watt
The unit of measurement of power for engines and motors. One horsepower equals 745 Watts.
Horsepower
The use of force to move an object over a distance.
