Kelvin's statement of second law of thermodynamics
Physics; General physics
It is impossible that, at the end of a cycle of changes, heat has been extracted from a reservoir and an equal amount of work has been produced without producing some other effect.
Kepler's first law of planetary motion
Physics; General physics
Each planet moves in an elliptical orbit, with the sun located at one of the foci.
Kepler's second law of planetary motion
Physics; General physics
The radius vector joining the planet to the sun covers equal areas in equal intervals of time.
Kepler's third law of planetary motion
Physics; General physics
The square of the period of a planet is directly proportional to the cube of the radius of the semi major axis of the orbit.
