Q:

What is wind resistance?

A:

Quick Answer

Wind resistance, a type of friction also known as drag, is the relative opposing force imparted on an object as it moves against still air. The wind resistance on an object depends on the square of its velocity, so as the object accelerates, its velocity and wind resistance increase.

Full Answer

Wind resistance is generated by all the exposed surfaces of the object, as it travels through the air. The shape of the object also contributes to the amount of wind resistance the object experiences. As more streamlined shapes, such as those of airplanes, rockets and high-performance automobiles, force the air around the objects surface, as to reduce the effect of wind resistance on their movement.

  • Q:

    What is the upward force on an object falling through the air?

    A:

    The upward force acting upon a falling object is called air resistance, according to Georgia State University. Often referred to as drag in aerodynamics, air resistance works in the opposite direction from which an object is moving.

  • Q:

    How does air resistance affect the acceleration of falling objects?

    A:

    Air resistance, also called drag, acts upon a falling body by slowing the body down to the point where it stops accelerating, and it falls at a constant speed, known as the terminal velocity of a falling object. Air resistance depends on the cross-sectional area of the object, which is why the effect of air resistance on a large flat-surfaced object is much greater than on a small, stream-lined object.

    What is fluid friction?

    A:

    Fluid friction is the resistance to an object's motion through a liquid or gas. When the motion is occurring in a liquid, it is referred to as viscous resistance. Resistance to an object moving through a gas, such as air, is termed air friction.

    What is static friction?

    A:

    Static friction is the resistance to movement when two non-moving solid objects are in contact with each other. Static friction matches applied force and prevents motion. When the applied force overcomes static friction, the object starts moving, and at this point, static friction ceases and kinetic friction comes into play.
