1. The problem statement, all variables and given/known data Coriolis Force - Explain how the following situations would appear in both the inertial and non-inertial reference frames. Assume the inertial frame to be a view from above. Situation 1 - a ball is thrown from the centre of a merry-go-round which is rotating counter-clockwise to a person on the outside. Situation 2 - the person from the centre now walks to the person on the edge. 2. Relevant equations None given. 3. The attempt at a solution Situation 1 I think I can explain. The view from above (inertial) will see the ball go in a straight line. From the non inertial frame it would appear to curve to the right since the person on the outside is moving faster than the person from the centre. Situation 2 I am really struggling with. I know it's different because we are dealing with a person in contact with the merry-go-round. From reading around I think the inertial view from above would see the person walk in a curved path but I can't explain why. I thought that only non-inertial frames see a curved path. I know that as he walks out he will be stepping onto faster and faster rotating ground but so long as he doesn't slip wouldn't he just walk in a straight line? Thank you for any help as I am struggling with this!
