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.
If you think that is no big deal, then think again. Unless you have tracked steps using a pedometer, you probably have no idea how many steps you take in a day. On average, 2000 steps is about a mile so walking 10,000 steps means walking about 5 miles. 10,000 Steps.
