| Aerodynamic | Having a shape that is not adversely (negatively) affected by wind or water flowing past it |
| Aerodynamic | Having a shape that minimizes drag and moves easily through air or water |
| Drag | It is the force (push or pull) going in the opposite direction of the movement of the object |
| Drag | An aerodynamic force that resists the motion of an object moving through air or water |
| Eddies | The small currents that are created behind an object as it travels through the air or water |
| Square | This shape would have a lot of drag as it moved through air or water |
| Gravity | Without air resistance, everything falls at the same rate. This is because ______________ is a constant force. |
| Airfoil | This shape would have a minimal(very little) amount of drag as it moved through air or water |
| Raindrops | The airfoil shape was originally discovered by observing this natural phenomenon |
| Airfoil | Having a body shape similar to an _____________ allows the fish to be able to move easily through the water |
| Air resistance | The drag caused as an object moves through the air |
| Size, Shape, and Weight | Air resistance is affected by an object’s ________, _______ and ________ |
| Vacuum | The only place where there is no air resistance |
| Sphere | This shape would have a medium amount of drag as it moved through air or water |
