GyanMul Prep · NEB +2 · Science · Grade 12

Physics (Science, Grade 12)

Everything on these tabs is Physics (Science, Grade 12) only, within NEB +2 Science · Grade 12.

Chapter 1 of 25 · Physics (Science, Grade 12)

Rotational Dynamics

7 topics
Board exam — Mechanics, 13 marks across 3 chapters
24 solved questions

Rotation treated the way translation already was: an angular set of the equations of motion, moment of inertia in place of mass, torque in place of force, and angular momentum conserved when no external torque acts.
