Friction is the force that opposes motion between any surfaces that are in contact. There are at least four types of friction: static, sliding, rolling, and fluid friction. Static, sliding and rolling friction occur between solid surfaces. Fluid friction occurs in liquids and gases

Static friction occurs when an object is resting on a surface. The static friction between the boots and the snow allows this person to stand and shovel snow.

When you rub your hands together you experience sliding friction.

When you ride a bike you depend on the rolling friction of the tires.

Sky diving depends on fluid friction between the air and the parachute to slow down.

In this video, I cover many real-life examples of friction and how friction helps you in everyday life.
