A) ​Drag
B) ​Lift
C) ​Pull
D) ​Friction

Quizplus · Accepted Answer

Drag is the force of air resistance acting opposite to the direction of motion of a moving object. It is the force that opposes the motion of an object through a fluid (such as air or water) and is caused by the friction between the fluid and the surface of the object. Lift is the upward force that opposes the weight of an object and is generated by the flow of air around an object. Pull is a generic term that can refer to any force that is pulling an object in a particular direction. Friction is the force that resists motion between two surfaces that are in contact with each other.
