Chapter 2: Motion in a Straight Line
NCERT Class 11 Physics, Part I, Chapter 2. 4 lessons, 9 narrated 3D videos, 4 simulations and 8 quiz questions, following the textbook section by section.
- Instantaneous velocity and speedA car drives along a straight road. To describe where it is, we first need a reference point. Let us call it O, the origin.
- AccelerationAn auto-rickshaw pulls away from a traffic light. Its speedometer climbs: 0, then 2, then 4, then 6 metres per second, one step every second.
- Equations of uniformly accelerated motionA car starts with velocity u and has a constant acceleration a. Its v–t graph is a straight line that starts at height u.
- Relative velocityYou are sitting in a train at a station. The train on the next track starts to move, and for a moment you are not sure which train is moving. Motion depends on who is…
