According to Newton's law of gravitation...

According to Newton's law of gravitational, every particle of matter attracts every other particle. But bodies on the surface of Earth never move towards each other on account of this force of attraction. Why ?

Text Solution

Verified by Experts

According to Newton's law of gravitational, the gravitational force between two particle//bodies of masses `m_(1)` and `m_(2)` placed distance `r` apart is
`F = (G m_(1)m_(2))/(r^(2))`
Since the masses of particles are very small, the gravitational attraction between them is too small tp produce any motion in them.
Due to the large mass of Earth, the gravitational attraction between the bodies and earth is quite large due to it, the bodies are attracted towards the centre of earth.

Do particles of matter attract each other ?

According to Newton's law of gravitation, every object attracts every other object. Thus, if the earth attract an apple towards itself, the apple also attracts the earth towards itself with the same force. Why then does the apple fall toward the earth, but the earth does not move towards the apple ?

    According to Newton's law of gravitational, everybody in this universe attracts every other body with a force, which is directly proportional to the product of their masses and is inversely proportional to the square of the distance between their centres, i.e., F prop (m_(1)m_(2))/(r^(2)) or F = (Gm_(1)m_(2))/(r^(2)) where G is universal gravitational constant = 6.67 xx 10^(-11) Nm^(2) kg^(-2) . (i) What is the value of G on the surface of moon? (ii) How is the gravitational force between two bodies affected when distance between them is halved? (iii) What values of like do you learn from this law?
