IB Physics. Same Acceleration? Think again!

Most people assume that if two masses are connected by the same rope, they must have the same acceleration. That intuition is wrong. In this video, we analyze a simple pulley system and uncover the actual kinematic constraint — using logic, geometry, and reasoning instead of memorized formulas. No exam tricks. No shortcuts. Just real physics thinking. If you’re post-school, early undergraduate, or someone who enjoys understanding why physics works — this is for you.
