Make the shape more aerodynamic; use a less frictionable surface; go to a higher altitude (for aircraft only); travel slower than Mach 0.5.
using controller to control it.. decrease weight to reduce drag
lift decrease and increase drag
In general (special exceptions may apply) increase speed = increase drag.
it decreases!
Gravity, friction, or wind drag.
A simple way to put it would be; - Decrease drag - Improve propulsion
It will use its engine power to increase thrust and to decrease drag.
To reduce drag, you can streamline the shape of the object, minimize surface roughness, and reduce the frontal area exposed to the flow of air or water. Additionally, reducing speed can also help decrease drag forces.
Spoilers decrease gas mileage. Spoilers are designed to create down force, which creates drag. The drag will increase gas usage.
The speed of a drag-line might me unable to know because of all of the add-ons you can add on it and the speed might allways increase and decrease.
when we use parachute, the wide surface area can decrease the velocity of the fallen object. thus, the drag force will also decrease. consequently, acceleration will be zero when the velocity is constant. finally, the object can land more safely without huge impact.
the car was finely tuned to decrease its drag coefficient.
