Name: Review of Mechanical Energy and Momentum Equations and When To Use Them! Category: Momentum and Collisions Date Added: 2017-02-16 Submitter: Flipping Physics By the time students learn about all the equations for mechanical energy, momentum, impulse and impact force, they often start to confuse the equations with one another. This is a straightforward, simple look at all of those equations and when to use them. This is an AP Physics 1 Topic. Want Lecture Notes?

http://news.discovery.com/space/astronomy/revolutionary-new-view-of-baby-planets-forming-around-a-star-141106.htm An article discussing recent findings of being able to watch as a new solar system is formed. Prior to this, much of planetary formation theory had been speculative. And now here we are, watching applications of g = GM / (R+h)^2 get modeled right before our very eyes! -
