What is the force that opposes the motion of an object through a fluid like air or water?
Drag force
What is the term for the constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration?
Terminal velocity
What does Newton's second law of motion state?
The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass
