For both, remember that velocity is a vector force, meaning that it has both a magnitude and direction. Since direction is part of the vector, if the direction changes so does the velocity in general. The changing of velocity is acceleration, so for 1 the answer is False.

For 2 I'm not sure what you meant, but the answer is the acceleration changes but the velocity does not.
