Questato 1-7 tomorrow PHRESH PHYSICS

Please discuss any questions you have about the ws you should be able to

  • draw FBD
  • Write a stupid equation based on the FBD
  • determine forces
  • calculate accelerations
*note if you have not completed part c please do so.  you may post and discuss your answers.

  1. Does anyone remember the name of the triangle he showed us in mod 7? It was somebody's last name.

    1. A stupid equation is an equation so simple that it's stupid.
      Example: Fg+Fn≠0
      Also it's 1-7 in the Force Diagrams and Net Force packet.

    2. A stupid equation is something like F=F. Something that we normally don't think of as an equation but that can really help you figure out a problem.

  3. Can you post the answers to the accelerations for #7 in the packet?

    1. For 7 c. I got that the acceleration for system A was 4.9m/s/s, for system B 3.3 m/s/s, for system C 6.53 m/s/s

    2. How did you get the answer? I don't understand how to calculate the acceleration. I know that it involves net force but I don't understand how to calculate the net force or anything without actual numbers on the systems.
