Question

is the moon attract the earth. why does the Earth not move towards the moon?​

Answer 1

Explanation:

I said the gravitational force on the moon would be "sideways" if the moon moved in a perfect circle - but it doesn't. Let me draw an exaggerated diagram of the Earth moon system with a non-circular orbit.

Maybe it is difficult to see, but in this case the gravitational force on the moon is NOT perpendicular to the velocity. What happens in this case? Well, part of the gravitational force is in the same direction as the velocity, the moon will increase in speed. Also, since part of the force is a sideways force, the moon will change direction. This is what happens with most orbits. The moon moves closer to the Earth and speeds up as it does so. As the moon moves away from the Earth, the opposite happens. This is part of the reason behind the Super Moon that was popular a while ago.

$\bf{\underline{\underline{Correct \:Question:}}}$

If the moon attract the earth. why does the Earth not move towards the moon?

$\bf{\underline{\underline{Answer:}}}$$<b><p style=color:red ">The earth and the moon experience equal gravitational forces from each other. However, the mass of the earth is much larger than the mass of the moon. Hence, it accelerates at a rate lesser than the acceleration rate of the moon towards the earth. For this reason, the acceleration produced on earth does not observe and hence we do not see the earth move towards the moon.</p></b>$
