Newton's law of cooling
qânun-e sardeš-e Newton
Fr.: loi de refroidissement de Newton
An approximate empirical relation between the rate of → heat transfer to or from an object and the temperature difference between the object and its surrounding environment. When the temperature difference is not too large: dT/dt = -k(T - Ts), where T is the temperature of the object, Ts is that of its surroundings, t is time, and k is a constant, different for different bodies.
Newton's law of gravitation
qânun-e gerâneš-e Newton
Fr.: loi newtonienne de la gravitation
The universal law which states that the force of attraction between any two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them: F = G (m1.m2)/r2, where G is the → gravitational constant.
