NCERT Class 8 Science Chapter 9 Friction Test Mock Test

This free online test covers Chapter 9, Friction, from the NCERT Class 8 Science textbook. The 30 questions are written directly from the chapter — definitions, processes, worked examples and the points the book italicises — so a score here tells you how much of the chapter actually stuck, not how well you guess. Each answer carries an explanation that says why the right option is right and why the other three fail, which is where most of the learning happens. Attempt it after your first read of the chapter, then again before the exam. There is no negative marking, and you can review the full solution the moment you submit.

Sample Questions

Q1.In Activity 9.1, a book pushed gently across a table stops after some distance whichever direction it is pushed. This shows that the force of friction:

  • AAlways opposes the applied force and the motion of the book
  • BActs only on the surface of the book and not on the table
  • CActs only when the book is pushed towards the left
  • DAlways acts in the direction the book is pushed

Q2.What causes friction between two surfaces in contact?

  • AThe weight of the air pressing down on both surfaces
  • BThe electrostatic charge that builds up between the surfaces
  • CThe irregularities on the two surfaces, which lock into one another
  • DThe heat produced whenever two objects touch

Q3.Why is the force of friction greater when a rough surface is involved?

  • ARough surfaces produce more heat and so slow objects down
  • BRough surfaces have no irregularities left to be worn away
  • CA rough surface is always heavier than a smooth one
  • DA rough surface has a larger number of irregularities to interlock
