Are gravity and gravitation the same thing?
Actually I have 2 teachers at my school. One of the said that gravitation is the force of attraction between any two bodies in the universe due to their masses and gravity is the force of attraction between one normal body and another heavenly body.
But the other teacher said that both the gravitation and gravity refer to the force of attraction between two bodies one of which is very much massive such as earth.
Which one of them is correct? Can anyone help me?
