There is! But because the Moon is only about a quarter the size of the Earth, the pull is not as great.
By the way, did you know the Moon is actually a chunk of the Earth that was knocked off in an inner planetary collision shortly after the Earth formed?

According to Newton, there is a gravitational force between every two sets of particles in the universe. This force may be so small that it could never be recorded. Since the moon is not small, compared to atoms that is, there is gravitational force there. This force is small compared to the Earth (1/6th) or to other massive bodies. If there was no gravitational force on the moon then when the astronauts jumped about, they would have kept on going.

There is always a garvitational force even in zero g. The force of gravity between two objects is related to a constant times the product of the mass of the two objects divided by the square of the distance between the two objects. What you get in zero g is that you are applying an opposite force (thrust) so that the gravitational force is cancelled.
So think of this, if you are standing on an asteroid, that asteroid has a gravitational force. The graviational force may not be enough to keep you on the surface of the asteroid if you jump because the mass of the asteroid may be too small compared to your weight. Your legs could be your rocket powered vehicle for propelling you into space!

There is one,it's just weaker than that of earth. The strength of the gravitational force of a body depends on the mass of the object. Thus,the moon has a weaker gravity due to it's smaller mass.

Moon does have gravitaional force but its 1/6 times that of the earth.its gravitational pull id greater on the side of the earth closer to the moon, and weaker on the other side.

I'm not sure where you heard this, but it is incorrect. The gravitational pull of the moon is one of the reasons we have tides (the sun's gravity is the other one). The moon's gravity is about 1/6th that of earth, so if you weighed 180 pounds on earth, you'd weigh about 30 pounds on the surface of the moon.

Yes, there is gravitational force on moon but is insufficient and less (1/6th) as compared to earth.

all mass has gravitational force.
think of gravity like a special type of static electricity (I know it is different, but just use this example...)
when a sock and wool pants coe out of the dryer stuch together, the sock is pulling on the pant leg just as much as the pant leg is pulling on the sock.
The human body pulls on the earth with a person's weight exactly the same amount that the earth pulls on the person.
in space with no gravity, two stationary but relatively close objects will pull together due to the gravity of both masses.

There is gravitational force on Moon and it is lesser than that on the earth. This is bcoz of density defference between moon n earth

moon definitely has gravitational force approximately 1/6 that of earth because its smaller in size as compared to earth.it is because of this gravitational force that we have tides
