Motion in a Plane: NEET questions with solutions
NEET uses this chapter for vector addition with the law of cosines, unit-vector algebra, projectile formulas (time of flight, maximum height, range, complementary angles) and centripetal acceleration. Marks are lost by adding magnitudes instead of vectors, treating the velocity at the top of a projectile's path as zero, and forgetting that uniform circular motion is accelerated motion.
Also called: projectile motion · 2D motion · vectors · relative velocity
