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.
At 5000 steps, the average American walks about 2.5 miles or about four kilometers each day: Pedometer Steps per Mile. Pedometer researcher Dr. Catrine Tudor-Locke published a study in 2004, showing a wide variation in the 200 men and women who participated. Men: 7192 steps per day.
