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.
However, with the use of smart pedometers, they were shown to increase physical activity by just over 2,000 steps, or about one mile of walking per day.2. For many, 10,000 steps may seem like a daunting task, especially since the average American walks about 5,900 steps. The Mayo Clinic recommends people using pedometers first set short-term goals, such as taking an extra 1,000 steps daily for one week, and then build up to a long-term goal such as 10,000 steps.1.
