Introduction to Newton's law of gravitation

so basically, Newtons Law states that every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Explanation: newtons law simplified in my opinion is a physical law that describes the attraction between two objects with mass.

hope this helps.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
