So I know non-uniform velocity as, "Non-uniform velocity is when an object covers unequal distance in equal interval of time in a particular direction or covers equal distance in equal interval of time but changes its direction" (am I correct?) and acceleration is "rate of change of velocity per unit time". So my question is are they same or different things and if different then how? In both scenario either direction changes or magnitude or sometimes both. So how they are different?
P.S: 1) Sorry If that is a dumb question but I was teaching my little brother and it just came randomly in my mind since then it is bothering me. 2) Excuse my English. (Not a native speaker.)
