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.
How many steps per day does the average adult take? Studies found that the average American adult only makes it about halfway to a goal of 10,000 steps per day, although those who wear an activity monitor pedometer seem to log more steps per day. If you walk between 5000 and 7000 steps per day, you are an average American.
