yes i'm with both of ya - I was gonna say its the heavy gyro action in a car's flywheel -its in the drivetrain B4 the tranny - and its maybe a ft. in diameter on ole v8's - havn't scene a 4-bangers smaller flywheel - but here is a useful analogy - the gyro action while spinning on one 'plane' - like in geometry,
imagin if u ever took your bike wheel off as a kid, held the axle bolts, and have your friend spin it fast in your hands - you won't even be able to tilt it off-axis in three dimensions its very powerful - and when combined in 3 diifferent planes of rotation - thats what forms a gymbal-gyro in early rockets - to keep them on track straight. It id one demostration of conservation of momentum or anyway
