, Gravitation
In 1666, Newton saw an apple fall and
wondered, "Why did it fall straight down?"
He realized a force must pull objects
toward Earth, the same force that keeps
planets in orbit. He named this force
gravity, leading to one of the greatest
scientific discoveries.
, Centripetal Force?
A stone tied to a thread moves in a circle due
to centripetal force, acting towards the
center.
Example: Earth's gravity provides the
centripetal force for the Moon's orbit.
Circular motion involves constant direction
change, altering velocity.
Centripetal force ensures circular motion,
preventing the object from moving straight.
The Moon's orbit is maintained by Earth's
centripetal force.
