For instance, the motion of a spacecraft, regarding its orbit and attitude , is described by the relativistic theory of classical mechanics, while the analogous movements of an atomic nucleus are described by quantum mechanics.
According to the NHS, the average Briton walks between 3,000 and 4,000 steps a day - significantly less than the Fitbit target. Yet many people do significantly more, and for them 10,000 steps might not be much of a target.
Wear a Fitbit tracker and determine how many steps you take on average each day over the course of a week. Thatâs your baseline. The Mayo Clinic recommends adding 1000 daily steps each week, so if your baseline is 4000 steps per day, set your goal at 5000 steps each day.
