They spent the period drawing free-body diagrams on the whiteboard with dry-erase markers — but also sketching stick figures spilling coffee. Then, slowly, they labeled forces: ( F_{\text{friction}} = \mu m g ). They wrote the kinematic equation ( v_f^2 = v_i^2 + 2a \Delta x ). They substituted, simplified, solved.

Jenna closed the old textbook. The margin notes in her grandfather’s handwriting — “algebra is just rearranging until it makes sense” — felt truer than ever. O-Meara J. Physics. An Algebra Based Approach 2...

“What forces act on the cup?” she asked. They spent the period drawing free-body diagrams on

“Not a chance,” laughed Lisa. “But now I can tell the ER doctor why the patient has second-degree latte burns.” O-Meara J. Physics. An Algebra Based Approach 2...
