Physics - Unit 2 Test

Hints §

Sometimes Mr.Gibbons drops hints before the unit test and I am going to write them here so I can review them the night before

• Graphical vectors will be on the test, although there’s some leeway
• On Vector Components and Static Equilibrium lab Figure A is going to be on the test
  • Which force is balancing in the vertical direction
  • if F1${}_y$ ≠ F2 then you’re doing something wrong
  • F1y = F1 sin $\theta$
  • F1x = F1 cos $\theta$
  • F1y + F2y = W
  • y = sin $\theta$
  • x = cos $\theta$
• #4 and #5 are on the test on the vectors worksheet
• Static Equilibrium #1 on the test
• Instead of weight holding it down a balloon is pulling it up
