they will not affect rotatation inertia. Without going into a physics lesson:So then heavier rotors wouldn"t affect rotational mass?
I disagree and this and here is why. Inertia is related to Mass but is more dependant on WHERE the mass is located. Why do you think ice skaters have to tuck in their arms and legs to spin so fast? The further away mass is from the axis of rotation (i.e. axle) the more impact it will have to the inertia. Rotors are right on the axle. Compared to the wheels and tires which spread further away from the axle and collectively weigh in around 50lbs each, the rotor has minimal impact on the Inertia.Isn't mass related to inertia? The larger the mass the more inertia. Acceleration is a change in speed or direction. It is easier to accelerate a smaller mass than a larger mass. I can be easily corrected, but according to Newton's second law of motion doesn't
acceration = force/mass? Acceleration and mass have an indirect relationship in that the
smaller the mass (inertia) the larger the acceration with the same force (force = m x a),
likewise, the larger the mass the slower the acceleration. If you have a car with 300 hp and 300 torque, the car with less mass will accelerate at faster rate.
With all that technical talk, I would put my money on the lighter car/with lighter brakes
accelerating at a faster rate. Let me know what you think?
