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 walk 10,000 steps a day, you will probably do more than 150 minutes and that's great: research suggests that the more activity you do the better, as regular exercise has many benefits. The average person walks between 3,000 and 4,000 steps per day. To find out how many steps you take each day, use a pedometer. If you have a smartphone, you may be able to download a pedometer app. Pedometers measure your every step: around the house, across the office, window shopping, to school or the park.
