heat from the earth, is near volcanoes usually.
the loss of energy during a conversion.
A result of a force moving an object a certain distance
the ability to do work.
energy of position
energy of motion
rate at which work is performed.
Is the study of the effects of work, heat flow, and energy on a system.
Transfer of heat between substances not in direct contact.
Transfer of heat between substances in direct contact.
First Law of thermodynamics
The law that heat is a form of energy, and the total amount of energy of all kinds in an isolated system is constant; it is an application of the principle of conservation of energy. Also known as conservation of energy.
Second Law of thermodynamics
A general statement of the idea that there is a preferred direction for any process.
The study of forces and their effects on a system in a state of rest or uniform motion.
Newton's 2nd law of motion
Newton's 3rd law
for every action force there is an equal and opposite reaction force.
object's center of mass or gravity
(when in) static equilibrium (an object is?)
is balanced at the center
modulus of elasticity (young's model)
Moment of Inertia
quantities that have both magnitude and direction
