Kinematics 2D(Projectile Motion) - NEET Previous Year Question with Complete Solution

NEET typically includes 1 to 2 questions from Projectile Motion (Kinematics 2D) in the Physics section each year. Based on NTA's official question papers from 2010 to 2024, this sub-topic has appeared in nearly every paper. Solving all available PYQs from this chapter gives you strong confidence and familiarity with the question patterns before the actual exam.

The horizontal range formula — R = u² sin2θ / g — is the single most tested relationship in NEET Projectile Motion questions. It directly involves the launch angle, initial speed, and gravitational acceleration. A close second is the time of flight formula T = 2u sinθ / g. Together, these two cover the majority of NEET marks in this sub-topic.

Projectile Motion is a Class 11 Physics topic, covered in Chapter 4 (Motion in a Plane) of the NCERT textbook. It falls under the Kinematics unit of the NEET Physics syllabus as defined by NTA. Students should complete this chapter before moving to Laws of Motion and Work-Energy Theorem, as it underpins several later topics.

Maximum horizontal range is achieved at a launch angle of 45°, given the same initial speed and ignoring air resistance. At 45°, sin2θ = sin90° = 1, which is its maximum possible value, making R = u²/g the largest achievable range. This result holds for projectiles launched from and landing on the same horizontal level.

Yes. Two launch angles that add up to 90° — such as 30° and 60°, or 20° and 70° — always produce the same horizontal range for the same initial speed. This is because sin2θ = sin(180°−2θ), meaning both angles give the same value of sin2θ. NEET has tested this relationship in multiple question formats over the years.
