understood what u mean.. but if u bring physics into the picture, then larger wheel would gvei u more momentum, hence once u're in motion, with more inertia u wouldn't even feel itz lagging.
itz the intially acceleration tatz different due to larger diameter...
itz the weight factor that plays quite a big role here, and of course.. along with the diameter of the wheel.
but anyhow, here is the xpert's explanation... i totally forgot my physic classes i had in college already. hahaha
The relationship between wheel size and acceleration is simple: bigger tires give you slower acceleration, while smaller tires give you faster acceleration.
This relationship is the product of the physics of converting the spinning motion of a motor into the forward motion of the vehicle.
Motors generate a “spinning” force (torque), which wheels convert into a “pushing” force at the point where they contact the ground. The larger this “pushing” force is, the faster the robot will accelerate.The relationship between torque and force is:
Force = Torque Distance from Center
to Edge of Wheel
A longer distance between the center of the wheel and the ground will produce a smaller force for the same amount of torque, hence the larger wheel (which has the longer distance) has a smaller force, and hence the slower acceleration.
but if u put weight into consideration, then it would be give a different result.. dont u thnik so? coz there is less mass to spin up. So, the car should feel little peppier when u accelerate.
but once u gain speed, the difference is pretty much negligible... unless u shed off more weight fr the car... u'll probably gain better mileage..
