Angular Motion of the System
Torque and Angular Motion
Systems rarely move in purely linear motion.
Usually, linear motion is accompanied by some degree of rotation.
Rotation occurs when the system is restricted to move around a fixed axis; therefore,

EXS 340 Barefoot Running
When wearing running shoes, do you rear foot or forefoot strike?
When I am jogging I rear foot strike but when Im sprinting I usually try to
forefoot strike because I reach top speed faster.
When running barefoot, do you rea
