Terminal velocity Flashcards
1
Q
Friction
A
Always acts in the opposite direction to movement. To travel at steady speed, the driving force must be balance the frictional forces.
2
Q
Drag
A
Is the resistance you get in a fluid(liquid or gas). Air resistance is a type of drag.
3
Q
How to reduce drag?
A
The most important factor in reducing drag is keeping the shape of the object streamlined. This allows fluid to flow easily across it, reducing drag.
4
Q
Terminal velocity
A
When the frictional force or and gravitational is equal to the acceleration force(resultant force is 0).
