(a) If we are moving at a high speed as the Earth revolves about the Sun (18.5 m/s, Example 2.3), then why don’t we generally feel this motion?

(b) Similarly, we are traveling through space because of the Earth’s rotation (1000 mi/h at the equator, Confidence Exercise 2.3). We don’t generally feel this motion either, but we do easily sense it otherwise. How?
