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.
Fitbit released data on the average steps per day for each U.S. state, based on over one million users, comparing summer to winter 2012 to 2014. Overall, Fitbit wearers walked 7,000 steps per day in winter and 1,000 more steps per day in summer, around an average of 8,000 steps. How Many Steps per Day Are Enough? The goal of 10,000 steps per day was not originally determined by research.
