Chapter 3: Motion in a Plane
NCERT Class 11 Physics, Part I, Chapter 3. 6 lessons, 14 narrated 3D videos, 6 simulations and 10 quiz questions, following the textbook section by section.
- Scalars and vectorsYour school bag has a mass of 5 kg. The classroom is at 30 °C. The period lasts 40 minutes. Each of these is fully described by one number and a unit.
- Adding and subtracting vectorsAn auto driver goes 4 km east, then 3 km north. How far is she from where she started, and in which direction?
- Resolving a vectorSometimes we only want to say which way, not how much. For that we use a unit vector.
- Motion in a planeA paper plane glides across the classroom. To describe where it is, we now need two numbers at every instant: x and y.
- Projectile motionThrow a ball forward. It rises, slows down, turns and falls back.
- Uniform circular motionSwing a ball on a string in a circle at a steady speed.
