Subdisciplines of mechanics include. 1  Statics, the study of non-moving bodies under known loads, how forces affect static bodies. 2  Dynamics the study of how forces affect moving bodies. Dynamics includes kinematics (about movement, velocity, and acceleration) and kinetics (about forces and resulting accelerations).
1 Researchers studied a group of men that typically walk approximately 10,000 steps per day (as measured by a pedometer) and asked them to reduce their steps to only 1,350 per day. 2  This meant taking elevators instead of stairs, driving to work and lunch.
Unsurprisingly, it's likely not a whole lot, especially since I live in Los Angeles, where nobody walks. As the New York Times explained in 2010, it is common for the health community to encourage people to walk 10,000 steps per day, which is about five miles. Researchers say it takes roughly 2,000 steps to reach a mile. But the average American only walks about half the recommended amount of 10,000 steps, according to Catrine Tudor-Locke, director of the Walking Behavior Laboratory at Pennington Biomedical Research Center.
