What's new in 2015?
1. Closed-caption made by myself! -- not the automatic subtitle anymore.
2. Learning objectives added for each video.
3. Quiz questions added -- including end-of assessment questions and preparatory, exploratory questions.
4. Mistakes fixed and cleaned up.
5. New examples/contents for selective videos.
My old videos and playlists will still be left on KZbin. Feel free to watch either one. Personally I think the revised videos are better mainly because of the subtitle.
Learning objectives of this video:
1. To introduce the principle of linear impulse and momentum and how to apply this principle to a particle or a system of particles.
2. To compare the principle of linear impulse and momentum to the principle of work and energy.
