The force that opposes the motion of objects is called friction. This force arises when two surfaces interact, resisting relative motion between them. Friction is crucial in daily life; it allows us to walk without slipping and enables vehicles to grip the road. There are different types of friction, including static friction (which prevents motion) and kinetic friction (which acts when motion is occurring). While friction can be a hindrance in some situations, it is essential for providing the necessary grip and control in various activities.
