An object can be designed to reduce air friction or drag by improving its aerodynamics, such as streamlining its shape to minimize resistance. Additionally, adding smooth or flatter surfaces can help reduce turbulence and drag. Employing materials with low friction coefficients can also help reduce air resistance.

How do you reduce drag?
To reduce drag, you can: Streamline the shape of the object to minimize resistance. Smoothen the surface to reduce friction. Eliminate unnecessary protrusions or features that contribute to drag.
How does friction relate to thrust?
Friction is a force that opposes the motion of an object. In the context of thrust, friction between the object and its surrounding surfaces can reduce the efficiency of the thrust by creating drag or resistance. Minimizing friction can help increase the effectiveness of thrust in moving an object.
How are airplanes designed to reduce drag?
Airplanes are designed to reduce drag by incorporating streamlined shapes and smooth surfaces to minimize air resistance. Winglets at the end of wings help reduce the formation of vortexes that create drag. Advanced materials and coatings are also used to reduce skin friction drag on the aircraft's surface.
How do you minimise the drag force?
You can minimize drag force by optimizing the shape of the object to reduce surface area, smoothing out sharp edges or rough surfaces, and using streamlined designs to minimize turbulence. Another way is to reduce the speed at which the object moves through a fluid, as drag force increases with velocity squared. Finally, utilizing materials with low friction properties can also help reduce drag.
What is the difference between drag and friction in terms of their effects on the motion of an object?
Drag is a force that opposes the motion of an object through a fluid, like air or water, while friction is a force that opposes the motion of an object on a surface. Both drag and friction slow down the motion of an object, but drag specifically affects objects moving through a fluid, while friction affects objects moving on a surface.
