Newton S Law Of Universal Gravitation — the NEET Physics formula with its derivation, variables, validity constraints and worked solver.
Newton's Law of Universal Gravitation Applicable to point masses or spherically symmetric mass distributions. Valid in the non-relativistic limit. Assume force is proportional to the product of masses. Assume force is inversely proportional to the square of the distance (Inverse-square law). Introduce the proportionality constant G. r > 0 m 1 >= 0 m 2 >= 0 Thinking gravity stops abruptly in space (it extends infinitely). Confusing 'g' (local acceleration) with 'G' (universal constant). Applying the formula to non-spherical objects close to the surface without integration.
