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?
Content Times:
0:14 Tacky Sweater Day!
0:22 Conservation of Mechanical Energy
0:54 Work due to Friction equals Change in Mechanical Energy
1:30 Net Work equals change in Kinetic Energy
3:01 Conservation of Momentum does NOT require the work due to friction to be zero
3:28 The initial and final points when dealing with momentum are predetermined
3:56 Impulse does not equal Impact Force

Nuclear energy might have a lot of unused potential. Not only is it one of the best mid-term solutions for global warming bit despite what gut feeling tells us, it has saved millions of lives. By investing more into better technologies we might be able to make nuclear energy finally safe and clean forever. (04:20)

Our hunger for energy goes beyond all limits and will double in the next 20 years. But what available technologies could meet the growing thirst for electricity? And will we also have to cut power consumption? What can Europe learn from China? And could "decentralization" into so-called "microgrids" the future of energy? (42.25)
