Study of fundamental particles and the forces of their interactions
A process cannot have as its sole result the transfer of heat from a cooler to a hotter body/In any closed system the entropy of the system will either remain constant or increase
Branch of physics/chemistry based on probability/explains how properties of atoms (mass, charge, structure) determine physical properties (conductivity...)
The study of the origins and evolution of the universe
Force x distance/also equal to the change in kinetic energy
Any type of back and forth motion where there is no damping (e.g. ideal springs/ideal pendulums/LC circuits)
The rate of heat loss of a body is proportional to the difference in temperatures between the body and its surroundings
Study of physical properties of earth
The study of physical properties of objects in space
The study of sound and waves
Any 2 bodies in universe attract each other w/force directly proportional to product of their masses & inversely proportional to the square of distance between them
The square of the period of an orbit is directly proportional to the cube of the radius
Study of the theory that all fundamental particles are vibrations of one-dimensional strings of energy in a higher-dimensional universe
Mass x g x height
It is impossible to reduce any system to absolute zero in a finite series of operations/A perfectly efficient heat engine cannot be created
The study of physical properties in low temperature situations, far below the freezing point of water
The change in energy of a system is the amount of energy added to the system minus the energy spent doing work/Law of Conservation of Energy
g (four words)
For every action there must be an equal but opposite reaction
Pseudo-force directed outward from center point
2 systems each in thermal equilibrium with a third system are in thermal equilibrium with each other
The sum of the forces equals mass x acceleration
Measure of force amplification achieved by using a tool (any mechanical device)/levers, gears, block & tackle/equal to Force Out/Force In or Velocity In/Velocity Out
Energy stored in a spring/by gravity/in a capacitor/in an inductor
Study of the physical properties of light
The sum of the potential & kinetic energy of an object
Circular motion where the speed of orbit is constant
Bodies in orbit will sweep out equal amounts of area in equal times
Describes the motion of points, bodies (objects) and systems of bodies (groups of objects) without consideration of the causes of motion
An object at rest will remain at rest and an object in motion will remain in motion until acted upon by an outside force/inertia
Study of physical properties of the atomic nucleus
Deals with the launching, flight, behavior, and effects of projectiles, especially bullets, gravity bombs, rockets, or the like
Study of motion of bodies in a frame of reference
One half mass x velocity squared/energy from motion
Laws of physics governing motion in its classical sense
Force toward a center point
Study of the physics of heat
Study of how electrons and photons interact at the quantum mechanical level
Study of systems where objects move at speeds very close to the speed of light
Orbits are ellipses with the body being orbited at one of the ellipse's foci
Measure of stiffness of elastic material/defined as the ratio of stress (force per unit area) to strain/also 'tensile modulus' or 'elastic modulus'
'Work/Time'/also equal to force x velocity
Study of physics in living systems
Laws of physics governing orbiting bodies/mathematically proven by Newton
Defined as useful work per quantity of energy or Work In/Work Out or Mechanical Advantage/Ideal Mechanical Advantage
Integral of force with respect to time/also equal to the change in momentum
Study where the smallest discrete values (quanta) of matter and energy become relevant
Reaction force described quantitatively by Newton's second and third laws/force applied on a surface in a direction perpendicular or normal to the surface/propellers & rockets
The study of space
Mass x velocity of an object
Analysis of loads (force and torque, or 'moment') on physical systems in static equilibrium or where components and structures are at a constant velocity
