Physics 9-3-21 Acceleration, Pt. 2 and Homework Review

PHYSICS: Speaking of sailboats, would you like to be on one right now? Good job with the derivations of acceleration formulas today! You’re doing really well with them – stay with it! Carefully examine what you know with the formulas you have that might fit. And if they don’t, examine what you do know that could lead you to what you need to know. You know? 🙂

This weekend’s problems may be a little challenging, but you can do it!! Do you need some extra practice rearranging the formulas, or just working the problems? Help session?

Chemistry 9-3-21 Using Density

CHEMISTRY – Great work with density today. Below is the lesson from today and below that is the help session from this morning.

Great review on density concepts and problems today, and more! 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.

When working these problems, don’t forget to follow the problem solving steps we discussed today:

  • 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?
