How Action-Reaction Applies to Biomechanics. Impulse:the product of the net force and the time interval for which the force acts. GRAVITATIONAL MOMENTS The moments that gravitational forces produce at L5-S1 depend on their moment arms. Putting that ankle weight on a patients leg will create an increase in the force of the mass and downward pull with gravity, the reaction is that the opposing muscle will have to create a force to overcome this mass. This will in turn increase the momentum of the tennis ball and increase the speed of the ball. Example 3: Therefor, the linear momentum of a particle is changed by the impulse of the resultant force on the particle. The purposes of these studies were to determine differences in total (TCF), medial (MCF) and lateral (LCF) tibiofemoral compartment compressive forces and related muscle forces between limbs (replaced, non-replaced, and control), and different slopes during uphill [0° (level), 5°, 10°], and downhill [0° (level), 5° 10°] using statistical parametric mapping (SPM). The task in many sport skills is to cause a large change in the velocity of something. Recently a colleague, Dr. Mike Lauder, and I published two kettlebell related research papers. is the application of force over a period of time to change the momentum of an object. 1. Impulse = Change of Momentum The "Impulse" part of this expression is a new quantity in our study of mechanics. It depends on both force and the time over which the force was applied. Units of impulse involve force and time: (Newtons * seconds).
