Motion in a Straight Line Class 11 CBSE Revision Notes
Motion in a Straight Line Class 11 Notes – The chapter teaches that path length transverse by an object between two points. Generally, the magnitude and displacement are not the same. Furthermore, the displacement depends upon only endpoints. Moreover, the path length depends on only the actual path. In addition, the displacement and magnitude are the same in one dimension because the two quantities do not change direction during the course of motion. Besides, the magnitude of displacement is less than the path length. Also, in a given interval of time, the average speed of an object is greater than or equal to the magnitude of average velocity.
Most noteworthy, the origin and the positive direction of an axis are a matter of choice. Also, if a particle is speeding up then the acceleration is in the direction of velocity. Furthermore, if the speed decreases then the acceleration is in the direction opposite of velocity. Moreover, the sign of acceleration does not tell that the speed of the particle is increasing or decreasing. Besides, the zero-velocity of a particle at any instant does not necessarily imply zero acceleration.
