Day 62: Forces and Kinematics

instructions

Physics 11 – Students have been scaffolded into doing unbalanced forces with kinematics.  Students’ biggest hurdle seems to be thinking about what is being asked and drawing a force diagram.  I often tell my students that the force diagram is where all of the physics happens.  After that, most of the work is algebra.

It’s been over a month since the students were working with kinematics, and now equations reign supreme.  Not one student resorted to using graphical methods of solving the questions.  Not surprisingly I heard several cries of “I don’t know what equation to use.”  I have no solutions to solving this issue.  Clearly there are some deep habits formed somewhere, where the equation is raison d’étre.
