State Newton's universal law of gravitation and write an expression for it.
Answers
Answer:
Explanation:
Newton's law of universal gravitation states that every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
♦ The universal law of gravitation states that every object in the universe attracts every other object with a force called the gravitational force.
♦ The force acting between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centres.
♦ Derivation : For two objects of masses m1 and m2 and the distance between them r, the force (F) of attraction acting between them is given by the universal law of gravitation.
