| 21. | In the drag force case, the relative wind speed decreases subsequently, and so does the drag force.
|
| 22. | For a rigid object, if the flow rate doubles, the resulting drag force on the object quadruples.
|
| 23. | Well, you need to know the drag force on the car and the amount of rolling resistance.
|
| 24. | Overall, ? is defined as mass divided by drag force ( mas per unit drag area ).
|
| 25. | Gravity will accelerate the bomb downwards, and as its velocity increases, so too does the drag force.
|
| 26. | But close to the ground, it only has to be strong enough to counteract the drag force.
|
| 27. | This occurs when the radial velocity has caused enough drag force to counter the centrifugal and buoyancy forces.
|
| 28. | Since the lift and the drag forces, and are scaled by the same factor to get and, =.
|
| 29. | That prevents important differential drag forces.
|
| 30. | This will generate lift force vector pointing forwards and upwards, and a drag force vector pointing rearwards and upwards.
