Here, students learn Newton's law of gravitation
and use this to study motion on an inclined plane, projectile motion and planetary (orbital) motion.
Milgrom  proposed an alternative explanation for the "galaxies rotation curves", by modifying Newton's law of gravitation
, for which he needed an ad-hoc introduction of a new constant of nature [a.
What a pity there weren't any school children there to watch me demonstrating Isaac Newton's Law of Gravitation
brings the concepts to the introductory and intermediate undergraduate levels, working primarily from first principles and beginning with Kepler's laws of planetary motion and Newton's law of gravitation
The exhibition's title refers to the gravitational constant, one of the most difficult values in physics to measure; although it appears in both Newton's law of gravitation
and Einstein's theory of relativity, it remains imprecise to this day.
Another consequence of gravity having an unrecognized short-range component would be that the exponent in Newton's law of gravitation
