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.
If you are reasonably healthy, 10,000 steps a day is a good goal for you. It is the equivalent of walking about five miles per day. (I say about because the actual distance depends on your stride.) You certainly don't have to take all those steps at once, but accumulate them over the course of the day.owever, your personal health, wellness, and fitness goals should play a factor in determining how many steps you strive for each day. For example, youth and adolescents should strive for a minimum of one hour of physical activity per day and oftentimes easily exceed 10,000 steps.
