Page 2 - Lesson Notes - Fluid Friction

Applications:
1. Hovercraft are faster than regular streamer boats. As hovercraft glides on a cushion
of air trapped under it. Air is less viscous than water so it offers less friction.
2. Special shapes (Streamlined shape) are given to objects moving with high velocity
in air and water to overcome fluid friction (drag).

Real-Life Examples of Fluid Friction
1. Swimming: A swimmer moving through water experiences resistance due to
fluid friction, which opposes their motion.
2. Airplane Flight: An airplane traveling at high speeds encounters air resistance,
a form of fluid friction, which affects its fuel efficiency and speed.
3. Stirring Coffee: Stirring coffee with a spoon encounters resistance from the
liquid, showcasing fluid friction.
4. Ship Movement: A ship sailing through water experiences resistance due to fluid
friction between the hull and water molecules.
