Exploring Forces
About this chapter
Exploring Forces is the second physics chapter of Class 8 Curiosity. Through Sonali and Ragini's cycling trip, children meet force as a push or pull that arises from the interaction of two objects. The chapter builds six core ideas: what a force can do (start, stop, change speed or direction, change shape), the difference between contact forces (muscular, friction) and non-contact forces (magnetic, electrostatic, gravitational), the SI unit newton (N), the role of friction and surface roughness, the difference between weight and mass, measuring weight with a spring balance, and floating and sinking through upthrust. CTET Paper 2 Science tests this chapter most often through everyday examples of force types, weight vs mass on different planets, friction-and-roughness scenarios, and Archimedes' principle. The four tests below — Practice 15 Q, Quiz 15 Q, Hard 15 Q, Mastery 30 Q — cover these ideas at the right depth and pace.
