1) Does it matter where you are in terms of radius (dist. from axis of rotation) on the merry go round with regards to angular speed?

2) Does it matter where you are in terms of radius (dist. from axis of rotation) on the merry go round with regards to tangential speed?

3) If I travel in a circle at a constant speed (according to my speedometer), then why does centripetal acceleration exist?

4) How do you know if acceleration exists when you get on/off the freeway without looking at the speedometer? How do you know centripetal acceleration exists when you make a right/left hand turn?
