WorldConservation of EnergyLet a coaster go from the top of its lift: height turns into speed, friction takes its cut, the loop asks for √(gr)
WorldCircular MotionGoing round needs a pull toward the middle: hold on and let go, ride a big wheel on a scale, take a bend on ice.
WorldPulleys, Ramps & WorkRig a block and tackle, haul a trolley up a ramp, time a winch: a machine trades force for distance, never saves work
WorldFree Fall & Air ResistanceRace a hammer and a feather through a vacuum, then ride a 45 m drop tower until the air stops you speeding up
WorldLevers, Moments & GearsBalance a playground seesaw, hang a crane's counterweight and climb a hill in the right bicycle gear
WorldBalance & Body Mechanics (Yoga)Drag a body with real masses into eight asanas and let its own mechanics judge you — joint angles, the stack of ear over hip over ankle, the centre of mass over the feet, a floor that is wherever the lowest point rests — then breathe with it and find the breath that swings the heart
