3-4 pieces of info about physics terms from qbreader
| Term | Definition |
|---|---|
| viscosity | It measures a fluids resistance to flow, "how thick it is" |
| friction | the force is directly related to mu |
| entropy | Always increases according to second law of thermodynamics |
| Albert Einstein | Proved E=mc^2 |
| entropy | This is denoted by the letter S |
| entropy | measure of the disorder within a system |
| Albert Einstein | He developed special and general relativity theories |
| Albert Einstein | his theories explained time dilation |
| Albert Einstein | 1905 was his "Annus Mirabilis" |
| Albert Einstein | He explained the photo electric effect |
| viscosity | it is a constant for a Newtonian fluid |
| viscosity | superfluids have a value of 0 for this |
| friction | it is the force that opposes motion |
| friction | this force can be reduced with a lubricant |
| friction | it has kinetic and static types |
| Ferromagnetism | Described in the Ising model |
| quarks | First theorized and named by Murray Gell-Mann |
| linear momentum | m*v, conserved in all collisions, symbolized p |
| linear momentum | According to Heisenberg's uncertainty principle, if you know position, you can't know this value |
| moment of inertia | this value times angular acceleration equals torque |
| gravity | General relativity attempts to explain this phenomenon |
| quarks | The types of them are up, down, charm, strange, top, and bottom |
| quarks | They are held together by gluons |
| quarks | They make up baryons, hadrons and mesons |
| ferromagnetism | Occcurs when the electron spins are all the same direction |
| ferromagnetism | This phenomenon does not occur above the Curie temperature |
| ferromagnetism | Cobalt, nickel and iron have this property |
| quarks | charge:2/3e or -1/3e |
| linear momentum | The ideal rocket equation is derived from this |
| linear momentum | Force is the derivative of this property with respect to time |
| moment of inertia | angular momentum over angular velocity |
| moment of inertia | rotational analogue of mass |
| moment of inertia | denoted by letter I |
| gravity | weakest fundamental force |
| gravity | causes acceleration at 9.81m/s^2 |
| gravity | It is an inverse-squares force |
| magnetic field | Its strength is measured in Teslas |
| magnetic field | denoted by the letter B |
| linear momentum | change in this quantity is called impulse |
