Basics
Energy of objects at rest
What is potential energy?
Thermal energy.
What is heat?
A "packet" of light energy
What is a photon?
The measure of unusable heat in a system
What is entropy?
The speed and direction of an object in motion
What is velocity?
The energy of objects in motion
What is kinetic energy?
The energy that comes from chemical reactions.
What is chemical energy?
Objects that can absorb heat quickly
What is a conductor?
Thermal energy, caused by the vibration of molecules
What is heat?
The three-dimensional expanse in which all matter exists
What is space?
The formula for work
What is force multiplied by distance?
Radiant energy.
What is electromagnetic energy?
Objects that absorb heat energy slowly.
What is an insulator?
Energy cannot be created nor destroyed
What is the law of conservation of energy (a.k.a. the first law of thermodynamics)
The amount of substance in a given space.
What is density?
The capacity to do work
What is energy?
The energy contained within an atom’s nucleus.
What is nuclear energy?
When all the thermal energy in a given area is evenly distributed.
What is thermal equilibrium?
The type of energy that all work eventually ends up as.
What is heat/thermal energy?
The mass and the velocity of an object.
What is momentum?
Something necessary for work besides a force.
What is movement?
The sum of both the potential and kinetic energies.
What is mechanical energy?
A property defined by how well an object absorbs or disperses heat.
Heat capacity
Heat always spontaneously moves from areas of high temperature to areas of low temperature.
The Second law of Thermodynamics
Something that is uniform at the molecular level
What is a pure substance?
