how can a particle hav tangential acceleration as well as radial acceleration simultaneously

in tangential acceleration , velocity would be changing , if v = r(omega), then how does this velocity change( i mean how does the velocity change with change in omega, should this omega change uniformly or non uniformly ?)
if it changes uniformly, then velocity remains constant , but how does it hav tangential acceleration?

is radial acceleration uniform or non uniform?
if suppose a body makes an angle theta with x axis, and in the next second, it makes (theta+aipla) with x axis and in the second second it makes (theta+2alpha) with x axis, then is this called uniform radial acceleration.

suppose the boay continues like that, then will it hav tangential acceleration also. if so, is it uniform or non uniform
