Study Notes

Gravitation

Sir Isaac Newton is credited with discovering the phenomenon of gravitation.
The story goes that Newton observed an apple falling from a tree and wondered why it fell vertically downward.
He concluded that the Earth attracts the apple towards itself, with this attractive force acting towards the center of the Earth.
Newton questioned whether this force of gravitation acts on objects at different heights on Earth and also on objects much farther away like the moon, other planets, and the Sun.

Force And Motion

Force is necessary to change the speed and direction of an object's motion.
Newton's laws of motion are relevant to understanding force and motion.
