Hey a few days back I was walking down on a slanting road and I felt like my feet were out of control I mean like I wonder why that happened. Do ya'll know?
Gravitation! It's because of the gravitational force!
'Course!
Gravity, also called gravitation, force that exists among all material objects in the universe.
That's right! Every object in the universe is surrounded by a gravitational field.
for any two objects or particles having non-zero mass, the force of gravity tends them to attract towards each other.
Well do u wanna hear a story 'bout it?
That's so cool!!
As well as the moon orbits earth in a circle. Circular motion also requires a force- A centripetal force. Newton realised that the force accelerating the apple is the same force keeping the moon in orbit.
So the story goes that Sir Isaac Newton deduced the law of gravitation upon seeing an apple fall from a tree. The apple accelerates as it falls. Newton realized that the force accelerating the apple must be coming from the earth itself.
