Question

1.ASSERTION- Velocity may be variable even if speed is constant.
REASON-Velocity is a vector quantity and speed is a scalar quantity.
2.ASSERTION- The displacement of the body is zero and distance of the body is non
zero when final position coincides with the initial position during its
motion.
REASON-Displacement depends upon the actual path traversed by the object during
motion.
3.ASSERTION- Distance-time graph of body is a straight line and motion of the body
is uniform speed.
REASON-Slope is the gradient of distance-time graph.
4.ASSERTION- A fixed point with respect to which the given object changes its
position is the reference point.
REASON-The motion of the body is not relative to the reference point.
5. ASSERTION- A body moving in a circular path has uniform velocity.
REASON-Velocity changes as the direction of motion changes.
6. ASSERTION: Displacement is a vector quantity.
REASONING: Displacement is described by magnitude but not by direction.
