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.
Experts say that while 10,000 steps a day is a good number to reach, any amount of activity beyond what you're currently doing will likely benefit your health.The origins of the 10,000-steps recommendation aren't exactly scientific.nstead, the agency recommends adults engage in 150 minutes of moderate activity a week, such as brisk walking. To meet the CDC's recommendation, you need to walk about 7,000 to 8,000 steps a day, Tudor-Locke said.
