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.
The average number of daily steps you take indicates your fitness level. If you take under 5,000 steps a day, you lead a sedentary lifestyle and may lack endurance. If you take between 5,000 and 7,499 steps per day, your lifestyle is on the lower active side. Taking between 7,500 and 9,999 steps daily indicates a somewhat active lifestyle. If you take between 10,000 steps and 12,499 steps daily, you have an active lifestyle.
