Spatial-numeric method application to the movable wedge problem for Physics First pedagogy

The objective is to solve the college physics problem of a block sliding down movable smooth wedge without friction anywhere using spatial-numeric perspective. drawing method used sum normal force and weight find acceleration. results are equivalent algebra within accuracy. result geometric construction with regular uncertainly was shown for case any horizontal applied force. For given force, an additional numeric graphing uncertainty in result. resuted solving via scaling concept modified gravity experienced by on wedge’s slant edge, assuming pre-requisite knowledge trigonometry. presented spatial imply Physics First pedagogy abilities, inclusion pre-projectile problem, pre-traffic-light post-collision one-semester syllabus.
