Video Discussion: Review of Mechanical Energy and Momentum Equations and When To Use Them!

Recommended Posts

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?

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

Thank you to Sophie Jones and her family for letting me use six of their sweaters in this video!
