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 older you get the more important it becomes. You can be very athletically fit, but if you are sitting all day with minimal walking or movement, your health will most definitely suffer. I personally walk about two hours a day or about 55 miles per week. In order to get fit, you still need to exercise in addition to your daily walks. 2  For optimal health and fitness, strive for 10,000 daily steps in addition to a regular exercise program including high-intensity interval training and strength training.
