Question on: JSS2 Basic technology - Introduction to Mechanics

Frictional force is the force that opposes the relative motion of two surfaces in contact. It plays a critical role in everyday activities, such as walking, where friction between our shoes and the ground prevents slipping. In vehicles, friction between the tires and the road allows for acceleration, deceleration, and turning. Without friction, it would be impossible to perform tasks that require grip and traction, making movement and transportation difficult.
