Friction: A Powerful Force Friction is a force that opposes the relative motion or tendency of motion between two surfaces in contact. It is caused by the irregularities and imperfections on the surfaces that interlock and resist sliding.

Types of Friction :There are three main types of friction: static friction, kinetic friction, and rolling friction. Static friction prevents an object from moving when a force is applied, while kinetic friction opposes the motion of an object that is already moving. Rolling friction occurs when an object rolls over a surface.

Importance of Friction: Friction plays a crucial role in many aspects of our daily lives. It allows us to walk, drive, and grip objects. Without friction, we would not be able to move or control our movements.
