Answer 1


Incorrect. Air friction cannot be in the same direction as the velocity.
INCORRECT

 The air friction cannot be in the same direction as the velocity of the object. return to top























Answer 2

Correct. Air friction is opposite the object's velocity.
CORRECT
 The air friction is opposite the direction of the velocity. return to top

Answer 3



INCORRECT

return to top

Answer 4




INCORRECT
Air friction will cause the object to travel toward the earth as will gravity, but the vector of air friction is not is this direction.

The force toward the earth is not air friction! return to top

What's this question really asking?

What is the relationship between velocity and friction vectors?
