Question

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

• A. Both statement I and II are correct.
• B. Both statement I and II are incorrect.
• C. Statement I is correct but statement II is incorrect.
• D. Statement II is correct but statement 1 is incorrect.

Answer 1

Answer: (C)

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