Is the workload from drag forces in deep water typically greater or less than that in shallow water?

When considering drag forces in water, it is important to understand how depth impacts these forces. In deep water, the workload from drag forces is typically greater due to several factors.

As water deepens, the movement patterns and forces acting on a body in that water change. The deeper the water, the more resistance there is from the water itself, especially when it comes to movements that create drag. In deep water environments, the potential for turbulence increases, and swimmers or athletes could encounter more friction and drag as they move through the water.

Additionally, in deep water, the velocity of movement can be higher and the surface area of the body in motion can create a larger interaction with the water molecules, resulting in additional resistance. This means that the physical effort required to move effectively in deep water is increased.

In contrast, shallow water may not exert the same level of drag because there is less water above the swimmer, which can reduce the overall forces acting against them. The nature of the water movement and fewer layers of water to displace contribute to a lesser workload in shallow depths.

Thus, the assertion that the workload from drag forces in deep water is greater than in shallow water is consistent with the principles of fluid dynamics and the experiences of athletes
