IB Physics Topic 6.2: Newton's Law of Universal Gravitation

This video begins by introducing Newton’s law of universal gravitation and the key formula, with a practice question. It then reviews electric fields and relates this to gravitational fields. This is followed by the distinction between gravitational field strength exerted and experienced, with an accompanying practice question. Lastly, a special scenario is covered, calculations involving an object between two masses at equilibrium and at non-equilibrium.
