Physics 11-12-19 Friction & Forces on an Incline Problems Review

PHYSICS: Boxes and block, all slipping and sliding… Is it starting to make a little more sense? Here’s an old review of of some of the homework problems from this chapter – #36, 40, and 41 (I think). Below the lesson is an old help session. It has #46 – the “girl on a sled coasts down a hill” problem.

You’re getting it…keep sledding and watch out for net forces!

Physics 11-12-19 A Look Back at Chapter 4 Concepts

PHYSICS: Leaves gracefully falling – can you apply concepts from this chapter to explain? Practice, practice practice the problems, but don’t forget the conceptual stuff! Here’s a short look (from last year) at some additional concepts.

How do parachutes work? What causes whiplash and how do seat belts work? If you get a chance, watch the Julius Sumner Miller videos on Newton’s 2nd law and 3rd law on You Tube. And also, here’s the link to the video clip I showed you on terminal velocity and the Physics of Skydiving I think they’ll all help a lot with the conceptual information
