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.
Do that for a few days and figure out your average daily steps. This is your baseline level of activity. Increase your walking time gradually, adding 10% to 20% to your daily average each week, he says. So if the first week you averaged about 4,000 steps a day, the next week shoot for 4,800 steps a day.
