Gravitational Force
- What is gravitation?? Have you ever think that why and how everything is stuck to the ground .
- It is a very strong presence about which we never think of it unless we are taught about it explicity in the schools.
- The phenomenon of action of attractive forces between two bodies by virtue of their masses is calles as gravitation
- In simple way it is a force of attraction i.e. one body attract other body towards it
- This force is creat or exist only because of EARTH'S gravitational force.The earth itself have a force of attraction because of which it attract or hold every other planet around it.Other planet also have some amount of attractive force (gravitational) but earth have in greater amount. So because of that weight on earth is greater than the moon
- That is why the whole universe is running in a proper manner
- About Gravitational force: When the sir ISAAC NEWTON is sitting under the apple tree, suddenly an apple had fallon on his head and at that moment his mind clicked that why this apple is fallen in the downword direction and not other(upside, left,right etc.)So from that incident he started to found the reason behind that. And after a long time he found out the reason and in this way production of gravitation word is on exist. Research for the gravitational force is the vast research in the newton's life i.e. founder of gravitational force. Defination of the gravitational force (G)
"The force which is directly proportional to product of the mass
and inversly proportional to square of the distance between them"

| Gravitational force |
- Gravitational force is denoted by -(G)
- For our simplicity we fixed the value for this G.The value is G=6.67*10^-11 Nm^2/Kg^2
- Some intresting facts about gravitational force
- It travel at the speed of light
- It is not true force in the nature
- It is only attractive and not repulsive force
- It is produce by both matter and energy
- It is ultimate source of energy in the universe
