The force know as gravity is one of the weaker forces. It only works between objects that are close together.
To explain another way, the moon is closest to you, so its gravity effect is stronger on you than the Earth's gravity. However, the earth is pulling on the moon, which is why it stays in orbit.
The Earth is not a magnet that may attract a body to the ground. The force of gravity of the Earth is balanced by the force of gravity of the other planets and the Sun. So you can walk. ( Einstein's famous equation.)
The force that attracts a body towards the centre of the earth, or towards any other physical body having mass
After crossing a hurdle, the direction of body weight is downward, towards the Earth, due to gravity. The body weight acts vertically downwards, providing stability and support as the individual lands on the ground.
its because of Earth's mass is greater than that of a body
Earth exerts a downward (towards the ground or Earth) force on your body. At the same time, your body exerts an upward (towards your body) force on the Earth. Your body is the one that seems to move, however, because the mass of your body is so much less than the mass of the Earth.
The forces due to gravity act along the line between the centers of two masses. That means that the Earth is attracted toward your center of mass, and you are attracted toward the center of the Earth, both with equal force. We typically refer to that direction as "down".
When the body falls freely towards the Earth, its total energy is constant. The body's kinetic energy increases as it gains speed, while its potential energy decreases as it moves closer to the Earth's surface. The sum of the body's kinetic and potential energy remains the same throughout the fall.
Acceleration due to gravity is due to the force of gravitation exerted on a body by the earth. All bodies get attracted towards the centre of the earth. So the acceleration is always pointed vertically downwards.
Anything in the universe that has mass, including you, me, a pencil, a piece of dust, all have gravity and are attracted to each other. Example: You are not just attracted toward Earth . . . the Earth is also attracted to you. From this can be said that objects with mass attract each other. It's just that you notice the gravity attraction from a large body like Earth because it is so huge. Also, Earth is close to you.
Gravitational Force
If you mean the Moon's movement around the Earth, the Earth's gravitation pulls the Moon towards the Earth. There is no opposing force that acts on the Moon (otherwise, the Moon wouldn't accelerate towards the Earth, i.e., change its direction).
The force acting on a body on Earth is the gravitational force. This force is directed towards the center of the Earth and is responsible for the weight of the body. The magnitude of this force depends on the mass of the body and the acceleration due to gravity, which is approximately 9.81 m/s^2 on the surface of the Earth.
