Physics 8-31-18 Acceleration

PHYSICS: Thanks Gigi and Joseph for the awesome illustration of constant acceleration! πŸ˜‰

Also – love how you began deriving formulas! I think you’ll come to find these are a ton better than some of the velocity problems you did. List what you are given and what you’re looking for – don’t forget things like “starts from rest” and “came to a stop.” Easy peazy! Okay, maybe not that easy! πŸ˜‰

Hon Chemistry 8-31-18 Another Look at Problem Solving

HON CHEMISTRY – Great job on the homework problems! Remember, in chemistry we use math as a tool, therefore we might work problems a little differently in chemistry than you do in your math class.

If you are converting, even if it’s not an “official SI conversion”, you MUST show your work using the Q Formula. When working other problems, don’t forget to follow these problem solving steps:

  • Analyze – write down what you’re given and what you’re looking for
  • Plan – write a formula where you isolate the unknown on one side by itself
  • Compute – plug in your data, numbers and units; then cancel the units, and if they cancel correctly, go on to the calculator. Be sure and give your answer what the correct units.
  • Evaluate – does your answer make sense, have you used the correct units, do you have the correct sig figs?

Have a great extra long weekend!!
