Class 8 Science — Chapter 5: Exploring Forces
72 practice questions · 24 Easy · 24 Medium · 24 Hard
Practise the most important Class 8 Science questions from Chapter 5, "Exploring Forces" — 72 NCERT-aligned multiple-choice questions with answers and explanations. The set is split into 24 Easy, 24 Medium and 24 Hard, so you can warm up on the fundamentals and then push into the exam-level problems that separate top scorers in CBSE Board exams.
"Exploring Forces" is one of the chapters where concept clarity across physics, chemistry and biology basics really pays off. Each MCQ on this chapter is timed and uses exam-grade marking (+4 correct, −1 wrong, 0 skipped), training the same negative-marking accuracy-under-pressure that real papers demand. Every question carries a short explanation, so a wrong answer becomes a quick lesson rather than a dead end — the fastest way to close gaps before a test.
Use this chapter as targeted revision: attempt the Easy set first to confirm your basics on Exploring Forces, then move to Medium and Hard to test application and problem-solving. Your accuracy, streaks and XP save automatically, and the chapter feeds into your overall Class 8 Science mastery score.

Key concepts: Exploring Forces (Class 8 Science)
This chapter explores forces — the pushes and pulls that shape the motion of everything around us. A force is measured in newtons and can change an object's speed, its direction of motion, or its shape; when forces cancel out they are balanced. Forces are contact forces (muscular force and friction, which act only on touching) or non-contact forces (magnetic, electrostatic and gravitational, which act across a gap). Gravity is the Earth's attractive pull, and the weight of an object is simply the gravitational force on it, measured in newtons.
- Force
- A push or a pull on an object, arising from its interaction with another object; its SI unit is the newton (N).
- Effects of a force
- A force can change the speed of a moving object, change its direction of motion, or change its shape.
- Balanced forces
- When two or more forces on an object cancel each other out, they are balanced and the object's state of motion does not change.
- Contact forces
- Forces that act only when objects are touching, such as muscular force and friction.
