Chemistry 10-31-19 Coding a Human “Robot” & HW Update

Posted on by

CHEMISTRY: So what’s more important than knowing something? Being able to use it? Being able to effectively communicate it to somebody else? Did you begin to feel the important of that today?!?

Here are some homework updates/clarifications:

  • Common Subst. Research – Due date changed to Tuesday
  • LAB: Energy of Solutions due tomorrow (Friday), 8:00 A.M. – Save as PDF to your Google Drive & Turnitin
  • Sciencegeek.com practice for Friday HW – Do Practice 1 only. Due Tuesday

Physics 10-31-19 Friction & Forces at an Angle

Posted on by

PHYSICS: So what happens to your applied for when you pull or push something at an angle?

Again, remember a few key things. One of the most important – net forces produce acceleration.

You can find Ff a couple of different ways – it’ll be part of a net force equation and can be found from the coefficient of friction equation. If and ONLY if your object is moving at a constant velocity, Ff will equal Fa. Fn is only sometimes equal to Fw. If your object is pulled at any angle (or pushed), Fn will be a part of Fnet in the vertical direction.

Whew! 🙂
