[[i]quote]Lift and drag are infinite in direction, either one can cause the motion of an object or oppose motion in any direction[/quote]


Lift is perpendicular to the relative airflow that caused it and drag is in the direction of the relative airflow that caused it


The first statement could be interpreted as contridictory to the second. The second statement is more accurate. Lift is created perpendicular to the direction of the object in motion. Lift is not created in front of the leading edge of a wing or in front of a golf ball and therefore is not "infinite in direction".
