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.
For example: 30 minutes gardening x 131 steps/minute = 3,930 steps. The general recommendation is to walk 10,000 steps per day. An average person has a stride length of approximately 2.1 to 2.5 feet. That means that it takes over 2,000 steps to walk one mile; and 10,000 steps would be almost 5 miles. A sedentary person may only. average 1,000 to 3,000 steps a day and would benefit by slowly adding more steps each day until they reach 10,000.
