Hey please help me with this question. In the equation a=v^2/r, when i increase the radius, the acceleration is decreased so acceleration is inversely proportional to the radius . However in the equation , a=w^2r, as increase the value of radius, the acceleration is also increasing. Where am I making the mistake ?
secondly, Using the equation v=wr , if I make r the subject r=v/w and then substitute it into the equation a=v^2/r, that gives me a=wv , will that be correct ?
