Physics question? Help

When a car rounds the corner at constant speed, the acceleration is zero.
True or false?

Thanks! :)

false..
acceleration depends on two things change in magnitude of velocity and change in direction of the velocity..
if either of one changes, acceleration is non-zero..

in the case of uniform circular motion(i.e the above case), an acceleration towards the centre of round acts and this is called as centripetal acceleration. If v is the constant speed,
centripetal acceleration = v^2/r , where r is the radius of the round.

i hope it helps..
and <3 you..
