drag forces

Drag force is the resistance an object experiences as it moves through a fluid, like air or water. It acts opposite to the direction of motion, slowing the object down. The amount of drag depends on factors such as the object's speed, shape, size, and the fluid's properties. For example, a streamlined bird experiences less drag than a flat-winged one at the same speed. Understanding drag helps in designing vehicles and structures to reduce resistance and improve efficiency. It’s a fundamental concept in fluid dynamics that affects how objects move through different environments.
