Kepler’s Laws:

Law of Orbits: Imagine planets moving in elliptical tracks or paths around the sun with the sun stationed at one of the foci.

Law of Equal Areas: Picture a line connecting a planet to the sun. As time passes, this line traces equal areas in equivalent time periods.

Law of Harmonies: Envision the square of the time it takes a planet to orbit the sun as corresponding to the cube of the planet’s average distance from the sun.
Centripetal Forces:

Think of centripetal forces as invisible elastics pulling objects toward the core of their circular journey.

For bodies moving in circular paths, the required centripetal force is linked to their velocity’s square and inversely related to the circle’s radius.
Galilean Law of Motion:

Imagine a marble on a slick floor. If undisturbed, it stays still. If given a nudge, it keeps rolling in a straight line endlessly.

When a force acts on a moving object, the extent of its acceleration directly corresponds to the force and inversely relates to the object’s mass.
The Gravitational Law:

Imagine every particle of the universe pulling on each other with an invisible rope—the stronger the mass, the stronger the pull.

This natural universal attraction, called gravity, works between any objects with mass, regardless of size or distance.
