Physics 12

On Monday we’ll have a short test on Kinematics. It will cover basic Kinematics Questions including an object thrown up and down and an object dropped.

We reviewed adding two vectors. On Monday I’ll also give you a small test similar to the example you saw in class today. You will need to:

– sketch the sum of the vectors

– find the sum by the Law of the Cosines and Law of the Sines

– find the sum by the Component Method

Then we looked at some applications of vectors. The first application is Relative Motion. The videos for this topic can be found under: Video Links for Physics 12.

I assigned the Problems on pages 72-75 of the SNAP book. Here are the solutions:

Pages 74-75

Then we looked at Projectile motion. We started with Projectiles thrown sideways. I assigned pages 78 – 79 #’s 1 to 6 of the SNAP book. Here are the solutions:

Pages 78-79

Then we looked at Projectile Motion at an Angle. All the videos for these are found under: Video Links for Physics 12. Make sure you understand this well. I assigned the problems on pages 82-83 and page 86. Here are the solutions.
