🧠 Memory Aid
The Three Laws as a Story:
Law 1 — "Stay Lazy": Objects are lazy — they stay as they are (rest or constant motion) unless a force makes them change. Inertia is physics laziness!
Law 2 — "F = ma": Force equals Mass times Acceleration. Remember the triangle: F on top, m and a on the bottom. Cover the one you want to find.
Law 3 — "Bouncer Rule": Every force gets a matching force back, on the OTHER object. Like a bouncer pushing you out — you push back on the bouncer with equal force, but on a DIFFERENT object.
Third Law pairs checklist — DOSE: Different objects, Opposite directions, Same magnitude, Equal type of force.
