Retarding force on a body moving in a fluid.
1Something must push the swimmer forward to balance the drag force.
2Actually, it is probably caused by the drag force I added in there.
3What happens to air drag force if I add mass to my bike?
4But there also is air drag force pushing against the direction of motion.
5Air drag force doesn't depend upon the mass of the object.
6Air Drag There must be a drag force on these disks.
7It occurs when the air drag force has the same magnitude as the weight.
8Here I will use the typical model for the magnitude of the air drag force.
9Here is a model you can use to find the magnitude of this drag force.
10That could lead to slight decreases in drag force.
11To keep things calm, I add a drag force.
12Once it leaves the cannon, it is going to have an air drag force on it.
13The air drag force increases with speed.
14Here I am showing the air drag force as being greater than the gravitational (weight) force.
15Both the pressure and the air drag force are proportional to the radius squared, so that wouldn't do much.
16In this case, the work done by the swimmer is equal to the drag force multiplied by the distance traveled.
