R= distance between the two non-zero masses. In the above formula of gravity, the notations are as follows:ДЇ= Gravitational force between the two non-zero masses. It has a value of the 6.674Г—10 в€’11 m 3 kg -1 s -2Д«y combining the equation one and the equation two Henry Cavendish has experimented and determined the value of the gravitational constant. It is the constant that is used to find out the attraction due to gravity between the two masses. The gravitational constant is represented by вЂGвЂ™. Newton has used the reasoning of the revolution of the moon in an orbit of a certain radius for deriving this law. It is the force which is inversely proportional to the square of the distance between them and is directly proportional to the products of the masses of the two objectsвЂќ. As per Isaac NewtonвЂ™s law of gravity вЂњ Gravitational force is the force by which every particle attracts every particle. The force generated due to gravity is termed to be the gravitational force. By observing the falling apple from the tree on the ground, Sir Isaac Newton was encouraged and he was able to derive the concept of the universal law of gravity. Sir Isaac Newton observed this force for the very first time. The atmosphere and the air in which we live are held by gravity. The gravity of the sun kept the earth in the orbit of the sun. Therefore, air resistance is more powerful on light objects than gravity, causing them to float a long time before landing.Gravity is the attraction force between the two objects. If you dropped a feather and a golf ball at the same time in a vacuum (space with no air), the feather would drop as fast as the golf ball. Similarly, leaves fallen off trees float in air for sometime before their landing. There is a lot of air resistance and that resistance makes the feather move slower. Gravity acting on the feather is too weak and it makes the feather float and fall slowlyДЄlso, when a feather falls, it falls slowly because the air is in its way. This makes the feather float and fall slowly. You know, heavier the object stronger the pull of gravity OR lighter the object weaker the pull of gravity.Д«ased on this, you can understand that the gravity acting on the feather is too weak to pull it towards the centre of the earth. The answer for this question is very simple. If gravity acts on all objects on Earth, how does a feather float and take a long time to fall? Sir Isaac Newton was an English physicist, mathematician and scientist, who was well-known as the founder of gravity. Without gravity everything would be floating here and there The following Gravity for kids lessonвЂ™s diagram shows you how everything would be floating here and there without gravity. Without gravity, you could jump into the air and keep moving into outer space! Thanks to gravity, what goes up must come down No matter how hard the girl tries to stay up, she quickly falls back.

Look at the following Gravity for kids lessonвЂ™s diagram. No matter how hard you jump, gravity will always cause you to fall back to the ground.

The following Gravity for kids lessonвЂ™s diagram shows you how does gravity work on the things on earth and how they are pulled towards the centre of the earth.Д®arthвЂ™s gravity constantly pulls you toward the ground This is because gravity constantly pulls you toward the ground.
