This section of the motion in one dimension or rectilinear motion deals with the motion where the body is subjected to non-uniform acceleration, i.e. in some part of the motion the body tends to move with some acceleration, while the other part of the motion body tends to move with some other acceleration. It is also advisable to the students that such motion is well understood if the student draws an acceleration-time graph first and then tries to solve the problem.
