Force
12/9
 LT: I will be able to apply understanding of frictional
forces through experimentation
 Vocabulary:
 Coefficients of friction, inclines
 Agenda
 Tension and Friction Lab—Assessment of lab skills
 Homework: Test Review Questions
 Should you push or pull a sled if you are on flat
ground? Provide force diagrams to prove your point
 Because the frictional force is proportional to normal
force the frictional force will be less if you pull the
sled, so you exert less force to pull her.
