What did Isaac Newton discover when the apple supposedly fell on his head?
A
Gravity
B
Electricty
C
Hydrogen
D
Plasma
Explanation: 

Detailed explanation-1: -"He showed that the force that makes the apple fall and that holds us on the ground is the same as the force that keeps the moon and planets in their orbits, ‘’ said Martin Rees, a former president of Britain’s Royal Society, the United Kingdom’s national academy of science, which was once headed by Newton himself.

Detailed explanation-2: -On a warm evening in 1666, just after dinner, the soon to be famous Isaac Newton sat down beneath this tree outside of Trinity to mull over his thoughts, when all of a sudden he was struck on the top of his head by a large, red apple. ‘Eureka’, he cried, and Gravity was discovered.

Detailed explanation-3: -In Principia, Newton described gravity as an ever-present force, a tug that all objects exert on nearby objects. The more mass an object has, the stronger its tug. Increasing the distance between two objects weakens the attraction.

Detailed explanation-4: -An apple moves towards the Earth when there is nothing holding it up, due to Earth’s gravitational force. We know that the apple also exerts an equal force on Earth.

Detailed explanation-5: -It was a scion of the original apple tree grown in the garden of Woolsthorpe Manor, near Grantham in Lincolnshire, which, it is said, inspired Sir Isaac Newton to formulate his theory of gravity by watching the fall of an apple from the tree.
