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.
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.
