Friction – it’s that force that’s always trying to stop us in our tracks. ⚙️ In NCERT Solutions for Class 8 Science Chapter 12, students learn about the force that resists motion and how it plays a huge role in our everyday activities.
What is Friction?
Friction is a force that resists the relative motion of two surfaces in contact. It can be helpful (like when brakes slow down a car 🚗) or annoying (like when you’re trying to slide a heavy box across the floor and it won’t budge 😤). The chapter explains how friction comes into play in different scenarios, from walking to using machines.
Types of Friction
There are several types of friction, including static friction (the force that prevents objects from starting to move) and kinetic friction (the force that slows down moving objects). The chapter explores each one in detail, explaining how friction works to either help or hinder motion.
Reducing and Increasing Friction
While friction can be a pain sometimes, we can also reduce it (using lubricants or making surfaces smoother) or increase it (like adding treads to tires for better grip). The chapter shows how understanding friction is crucial for everything from car safety to playing sports.
