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.
