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.
It is recommended that you begin walking as much as feels comfortable to you, then aim to walk in increments of 1,000 to 2,000 steps more each week until you're comfortably at 10,000 steps a day. There is nothing stopping you walking more than this each day, but the aim is to always make 10,000 steps.
