Question

Q i)The tangential acceleration changes the speed of a particle
whereas the normal acceleration cheanges its direction state
whether the statements are true or false
ii) at a certain moment the angle between velocity vector v and the
acceleration vector a of the particle is thyta what will be the
motion of the particle at this moment for diffetrent thyta's
rectilinear or curvilinear, acelerated or decelerated?

i)  The statement is false because tangential acceleration changes the    velocity not speed and normal acceleration is directed towards the centre    of circular motion
 ii)   The motion of the particle is curvilinear for example the projectile motion
