Part 4: Food for Thought.
In 1687 Sir Issac Newton published his book Philosophiæ Naturalis Principia Mathematica and in it were his three laws of motion. The second law as he defined it stated: that the net force acting on an object is equal to the product of its mass and acceleration, or F = ma. This law can be used to explain how an object's motion changes when an unbalanced force acts on it. When it comes to cycling these days there is a great deal of focus on that force, or as many of us have come to know it “power”. The formula for power is Force x Angular Velocity = Power and in actual fact our power meter doesn’t “measure” power, rather it measures Force and Angular Velocity and then multiplies one by the other. In cycling however power, or the force we act out against an object, is not the entire story when it comes to the control we have over this particular law or equation. We also have control over the Mass upon which the force is going to be applied, and in many cases in today’s endurance environment it is manipulation of the amount of this mass that offers the greatest radical improvement in performance for the majority of participants in a mass start race like the Marji Gesick.
