Mon Jan 30 Phys 221 SI Session New Terms/Equations Forces Normal: Perpendicular or “normal” to surface Always opposes motion Friction: In this class, mostly just in ropes Tension: Force due to gravity Weight: Newton’s Laws Body at rest stays at rest & body in motion stays in motion in same direction unless acted upon by a force Problems m = 12kg = Ɵ π/6 rad
