If the particle moves in a circle are its tangential acceleration and normal acceleration equal?

[PequodLZ]

And there's also the reverse, does a particle move in a circle if the tangential acceleration and normal acceleration are equal? or not necessarily?

 

[Dr.Peterson]

Why would you think this would be true?

What is the tangential acceleration for uniform motion in a circle?

What is the tangential acceleration for uniform motion in a circle?

Ah right its zero.
