Ok so my physics teacher was telling us about the gravitation and he gave us an example of two people standing and he said that these two people are attracting each other. Then he calculated the gravitation force between them. It was a clear thing for me until this. but then he said that they both don't move from their places because they are pulling each other with an equal force and these both forces cancel the effect of each other. I am saying that they don't cancel out as they are attracting each other. But this force between them is so small that they are overcome by other forces like force of friction,air resistance etc. That's why they don't move from their places. because the same thing happens when we jump from a building and we are attracted towards the centre of the earth. Can anybody tell me who is right and who is wrong? And if i am right, do give some examples also. Thanks!
