Class 11 Physics — Chapter 4: Motion in a Plane
66 practice questions · 22 Easy · 22 Medium · 22 Hard
Practise Class 11 Physics Chapter 4, "Motion in a Plane", with 66 NCERT-aligned multiple-choice questions. The set is split into 22 Easy, 22 Medium and 22 Hard questions, so you can warm up on the fundamentals and then push into the exam-level problems that separate top scorers in CBSE Board exams, JEE Main, JEE Advanced and NEET UG.
"Motion in a Plane" is one of the chapters where numerical problem-solving, derivations and conceptual application really pays off. Each MCQ on this chapter is timed and uses exam-grade marking (+2 correct, −1 wrong, 0 skipped), training the same accuracy-under-pressure that real papers demand. Every question carries a short explanation, so a wrong answer becomes a quick lesson rather than a dead end — the fastest way to close gaps before a test.
Use this chapter as targeted revision: attempt the Easy set first to confirm your basics on Motion in a Plane, then move to Medium and Hard to test application and problem-solving. Your accuracy, streaks and XP save automatically, and the chapter feeds into your overall Class 11 Physics mastery score. A few sample questions are shown below; sign in free to practise all 66.
Key concepts: Motion in a Plane (Class 11 Physics)
This chapter covers vectors and two-dimensional motion — vector addition, projectile motion, and uniform circular motion.
- Vectors
- Quantities with magnitude and direction; added by the triangle/parallelogram law and resolved into components.
- Scalar & vector products
- Dot product A·B = AB cosθ (scalar); cross product A×B = AB sinθ (vector, perpendicular).
- Projectile motion
- Independent horizontal (constant velocity) and vertical (uniform acceleration) motions; the path is a parabola.
- Projectile results
- Maximum height, time of flight and range depend on the launch speed and angle; range is maximum at 45°.
- Uniform circular motion
- Motion at constant speed in a circle, with centripetal acceleration a = v²/r directed toward the centre.
Key formulas — Motion in a Plane
💡 Exam tips for Motion in a Plane
- Treat projectile motion as two independent 1-D motions (horizontal uniform, vertical accelerated).
- Maximum range occurs at a launch angle of 45° (for level ground).
Sample questions
Which is a scalar?
Mass has only magnitude.
Two perpendicular vectors of magnitude 3 and 4. Resultant:
√(9+16)=5.
Dot product of perpendicular vectors:
cos 90° = 0.
