Newton Schmewton (Forces Pretest) Key
Check the key for the following errors:
5. the best answer is (c), but it would be even better if it read “the force pressing the two surfaces together”
6. the answer should be 3.53 x 10^22 N. (c) is closest.
12. should refer back to question #11, not #14.
31.(a) the answer should be 5.4 not 5.5 (to two SF)
Random forces notes probably not from your class, and probably incomplete. Hey, I’m trying!

First Law: The Law of Inertia
Second Law: Force, Mass and Acceleration
Third Law: The Action / Reaction Law

Here is a neat little plug-in from Wolfram Alpha that will calculate the gravitational field strength, g. Try it out!
Try comparing Mt. Kilimanjaro to Baffin Island for example. Which is larger? By how much? Why?

Here is the Crash Course on sliding friction. Careful, the second half gets into a 2-D problem which is what we do in Physics 12.
