Answer 1

Consider a record spinning at 45rpm. That’s 45 revolutions per minute. Now slow it down to 1 RPM. Thats a whole lot slower at the edge, right? Now slow it down to 1 revolution per day. To give you an idea, normal clocks hour hands spin at 2 rpd. The earth spins at about 1rpd. This is why it doesn’t feel like anything, and why we don’t change location when we jump, along with all the other explanations of inertial conservation.
