Non-constant Forces
What questions could we ask about this graph of a weightlifter doing his thing?
Some ideas:
Why do the dotted lines seem to be the derivative of the solid ones?
Dotted or solid: which is height and which is velocity?
I like starting out vague - what's the same, what's different between the red and blue cases.
Then can ask about the work done, the average power delivered, the maximum instantaneous power delivered, reflection on how realistic the curve might be. ~Marco
Want to make sure my students see more non-linear graphs. For some questions on work and power. #iteachphysics pic.twitter.com/sy3dkxnvep
