Q. Statement I: For one dimensional motion the angle be tween acceleration and velocity must be $0^{\circ}$ or $180^{\circ}$.
Statement II: One dimensional motion is always on a circle

Motion in a Straight Line

Solution:

One dimensional motion is always along straight line. But acceleration may be opposite of velocity and so angle between them will be $180^{\circ}$
