Aero- → air
Hydro- → water
dynamic → study of forces and motion in fluids
foil → shape/surface designed to produce lift or force when fluid flows over it
Streamline → smooth path of fluid particle
If you see foil, think shape;
if you
see dynamic,
think study of flow;
if you see streamline,
think smooth shape to reduce drag
1. Submarine → Hydrodynamic
2. Kayak → Hydrodynamic & Streamlined
3. Motorcycle → Aerodynamic & Streamlined
4. Javelin → Aerodynamic & Streamlined
5. Airplane wing → Aerofoil (shape), Aerodynamic (motion)
