Document Summary
Momentum is a vector quantity, there is a direction associated with it. Someone has to be assigned a negative direction because going in opposite directions. The sign you dictate tells you who wins the race. in this example, if its positive, first person will win. if answer is negative, second will. 1. 1m a second is a normal speed for the average person. Fastest person on the planet ran 12 m/sec. Positive answer therefore small guy won the race. Sprinting is a good example of being powerful. Specific to distance and time athletes are traveling. Power in biomechanics: about strength but not that alone. amount of power is relative to force and velocity- a lot of force very quickly. Generating a lot of force, very fast. Train yourself to drive huge amounts of force but a little bit slower. Generating smaller amount of force but generating it at massive velocities. Depending on body positions/segments, can generate different amounts of force.
