Drag Object

The drag field affects moving objects only and it will always exert its force in the opposite direction to the object’s motion. Almost all motion is subject to drag of one type or another, so for realistic dynamics animation, you will usually need to use the drag field. Without drag, a body would continue its motion unhindered. A body such as a parachute would never slow down.

One characteristic of drag is that it always exerts its force in the option direction to the body’s motion. This trait is illustrated below.

Typically, a variety of drag forces will act on an object, as shown in the next diagram. Note that you will not have to concern yourself with all these drag forces when you define the drag field.

Drag is always applied in the opposite direction to the body’s motion.

Often a variety of drag forces will act on the same object.
