Engineering Entrance Exam

For P.A. College of Engineering and Technology (PACET), TNEA cutoffs vary by course and category. For example, in 2024, the last round closing rank for B.E. in Computer Science and Engineering was 71612 (General-All India), while for B.E. in Mechanical Engineering, it was 174379. Cutoffs are typically released round-wise during TNEA counselling. 

Linear motion is one-dimensional motion. It refers to motion in a single direction or in a straight line. In linear motion, the object either moves forward or backward along one axis, i.e. x-axis. For example - a ball dropped from a height vertically downward or a car moving straight on a road. Motion in a Plane refers to an object moving in two dimensions, usually along x and y axes. For example, a football kicked at an angle.

The angle of projection is used to find the trajectory, horizontal range of a projectile, maximum height, and time of flight. For example, the maximum range on level ground is given by the 45-degree angle.

The vectors like velocity, displacement, and acceleration act along different directions in the two-dimensional motion. Resolving the vectors into the vertical and horizontal components allows the application of one-dimensional kinematic equations in each direction separately. It helps solve the problems more accurately and also simplifies the analysis.
