Explain why objects moving in fluids must have special shapes?
When objects move through fluids, they have to overcome friction acting on them. In this process they lose energy. Efforts are, therefore, made to minimise friction. So , objects are given special shapes.
What human body system is responsible for moving the body?
The musculoskeletal system is responsible for moving the body. In involves both skeletal and the muscular systems.
Shifts the direction of free moving fluids such as air and water?
shift the direction of free moving fluids such as air and water is...............------------------------> CORIOLIS EFFECT:)
Do all fluids flow?
Fluids can move two ways, by aerodynamics and hydrodynamics. Aerodynamics refers to gas moving around solid objects. Hydrodynamics refers to liquids moving around solid objects. Example water moving in a turbine.
What causes the shifts in directions of free moving fluids such as air and water?
The shifts in directions of free moving fluids like air and water are mainly influenced by pressure gradients, temperature differences, and the rotation of the Earth (Coriolis effect). Changes in these factors can result in the fluid moving in different directions to balance out the forces at play.
Which type of muscle is responsible for moving fluids through urinary system?
Most of the force moving fluids through the urinary system comes from gravity. A set of smooth muscles are positioned around the bladder to help it empty, however.
What is Burnuli's princible?
the moving pressure is less than the pressure caused by surronding fluids. Burnmolis princible is responsible for flight.-Rebecca a
What are some examples of fluids moving through objects?
Examples of fluids moving through objects include water flowing through a pipe, blood circulating through blood vessels in the body, and air passing through a ventilation system. Fluid mechanics describes the behavior of these fluid movements within different structures and systems.
How are dogs flies dolphins and humans connected by fluids?
TThey all spend a lifetime moving through and breathing liquids
What two ways do fluids move?
Fluids can move through convection, where bulk movement occurs due to changes in temperature or pressure, and by advection, which involves the transport of fluid by a moving medium, such as a current or wind.
What are the key differences between Eulerian and Lagrangian fluids in fluid dynamics?
In fluid dynamics, Eulerian fluids are described based on fixed points in space, while Lagrangian fluids are described based on moving particles. Eulerian fluids focus on properties at specific locations, while Lagrangian fluids track individual particles as they move through the fluid.
What do you mean by drag forceexplain why objects moving in fluids must have special shape?
Drag force is a resistance force exerted by a fluid (like air or water) on an object moving through it. Objects moving in fluids must have a special shape to minimize drag force and enhance their motion efficiency. The shape is designed to reduce turbulence and separation of flow, which helps the object move through the fluid with less resistance.

Hot air moving up is an example of?
Hot air moving up is an example of convection, a heat transfer process where hot fluids rise and cool fluids sink. This process occurs due to the differences in density between the hot and cold fluids.
Do fluids exert friction?
Yes, fluids exert friction through a property called viscosity. Viscosity is a measure of a fluid's resistance to deformation or flow, causing adjacent layers of fluid to move at different velocities, creating friction between them. This frictional force is responsible for fluid flow resistance in systems such as pipes or air moving over surfaces.
Which friction force is exerted by the fluids?
The friction force exerted by fluids is typically referred to as viscous drag. This force arises due to the friction between the moving object and the fluid it is moving through. Viscous drag depends on the velocity of the object and the properties of the fluid.
