Class 8 Science — Friction Important Questions with Answers (Long answers)
Class 8 Science is the year force, pressure, friction and sound become numerical-friendly, while crop science and microbes stay descriptive. The rationalized book is shorter than older reprints; this hub follows the surviving chapters so you do not revise a deleted lesson for a 2026 periodic test. “Force and pressure class 8 important questions” and “microorganisms friend and foe MCQ” are the search lines these chips answer. Hidden keys, twenty questions a screen.
Friction opposes relative motion, depends on nature of surfaces, and is usually independent of area in the school model. Static, sliding and rolling; lubricants and streamlining. Friction is a necessary evil — walking needs it, machine heat hates extra of it. Do not quote Class 11 μ tables; stay qualitative plus one order-of-methods item. You are on Friction (Long answers), page 1 of 1 — 2 questions in this filter. Long answers model a five-mark write-up: definition, reason, one diagram or equation idea, and a closing line. Do not copy the whole block in the exam; steal the order. This view is for the night before a unit test. Phone layout: chapter chips scroll sideways, answers stay inside a tap, and the next page is a numbered link so Google and students both get a short URL. Updated for 2026 classroom practice on the rationalized NCERT.
