HOW GRAVITY HAS MATH IN IT
- Gravity is an invisible force that occurs between two objects.

HOW DOES GRAVITY WORK?
- Every object in the universe that has mass experts a gravitational pull, or force,on other masses.
- The size of the pull depends on the masses of the objects.
HOW TO FIND GRAVITATIONAL FORCE
- In order to calculate the gravitational force between two objects w/ masses of m1 and m2 the equation is where G is gravitational force,r is the distance between the two objects, and f is the magnitude of the force between the objects.
WHAT'S GRAVITIES FORULA ?
- F=Gm2 M2 /r2, where f is the force due to gravity, between two masses (m1 and m2) which are distance apart G is the gravitational constant.
HOW WAS GRAVITY DISCOVERED ?
- Isaac Newton discovered Gravity. He was thinking about the force of nature while watching a falling Apple.

Facts
- To leave earths gravitational pull behind, an object must travel 7 miles per sec our planets escape velocity.
- Unlike force,with its dark & light sides,Gravity has no duality, it only attracts never repels.
- Gravity is also the reason why earths spins around the sun
