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.
