Energy Flashcards
transfer of thermal energy from one object to another because of a temp. difference
heat energy
heat flows from __ to __
hot to cold
the measure of how hot or cold an object is compared to a reference point.
temperature
during collisions higher energy particles ____ energy and low energy particles ___ energy
lose , gain
thermal energy depends on the __,__, and ___ of an object
mass temp and phase (solid, liquid Gas)
transfer of thermal energy with no overall transfer of matter
conduction
conduction of glasses is __ than conduction of solids
slower
transfer of thermal energy when particles of a fluid move from one place to another
convection
transfer of energy by waves moving through space
radiation
All objects radiate ___
energy
as an objects temp ___ the radiation ___
Increases
First law of thermodynamics
heat spontaneously transfers from hot to cold
second law of thermosynamics
thermal energy flows from colder objects to hotter objects is work is done in the system q
third law of thermodynamics
absolute zero cannot be reached
Energy of motion is what kind of energy
mechanical energy
Energy that is relative position or is stored
Gravitational potential energy
the potential energy of something that is stretched or compressed
elastic potential energy
What are the 6 forms of energy
mechanical, thermal, chemical, electrical, electromagnetic, nuclear
Law of conservation of energy
energy cant be created or destroyed
a force acting through a distance
work
what is the formula to calculate work
W= F x D
work=force x distance
the unit of measurement for work is
jewels
unit of measurement for force is
newtons
how fast work is done
power
