comment How cold would a bowling ball near absolute zero make a room?
Thanks @LDC3. I'm logged in on my phone, so it is slightly cumbersome to scroll through all that Latex. I've fixed the errors now.

comment Why doesn't a car slide down a banked road when there is no friction?
@User58220 Well, yes. From the point of view of the car, it is at rest, and the road is moving. However, it experiences a force which is trying to push it outwards. This is the centrifugal force. Your analysis of the situation is exactly the same as mine, but in an inertial frame. If you're trying to make a point, please do so and spare me the riddles.

@User58220, The car is not an inertial reference frame, so no force does not entail no acceleration.

@User58220, the reaction is equal and opposite to the net force, so it cancels it out. This is why the car doesn't sink into the road. The reaction force is always perpendicular to the surface, so it is irrelevant when you're thinking about the car sliding down the road.
