That depends on what you mean by "fluids". Most people just mean "liquids" when they say this, but many scientists and engineers use the word "fluid" to mean both liquids AND gasses. That's because, from a practical standpoint, liquids and gasses act similarly, in ways that solid objects usually don't.
For example, both liquids AND gasses provoke drag effects.
Atmospheric drag affects anything that flies or even just waves in the air. It's effectively the friction or inertia of the air hitting whatever's moving through it. Drag always wants to slow things down - no matter which direction something's trying to go, drag acts in the opposite direction. This is a major concern of aircraft manufacturers and pilots. It's also one of the main reasons low-orbiting satellites eventually fail -- they're pulled down into the atmosphere so low that they start to spiral in (they're safely de-orbited before actually crashing, of course). Drag acts similarly in liquids, pulling against the intended motion. This is the force that you pull against while swimming.
Can drag happen in solids? Well... not on time scales we humans usually think of. On the other hand, geologists studying the Earth's mantle (the part between the crust and the core) talk about the mantle's "viscosity". That's the same word we use to talk about the gooey-ness of syrup and the fluidity of vegetable oil. On long time scales, scales meaningful to the buildup of stresses in the Earth, the solid Earth can act like a fluid, flowing slowly under pressure. In that case, it wouldn't be exactly inappropriate to use the word "drag" with a solid... but frankly, it's just not done. After all, what would be dragging THROUGH a solid body like the Earth?

What is frictional force exerted by fluids called?
The frictional force exerted by fluids is called drag force. This force acts opposite to the motion of an object as it moves through a fluid, such as air or water, and it can affect the speed and direction of the object.
What air and water resistance are both sometimes called?
Air resistance is also known as drag, while water resistance is often referred to as drag or hydrodynamic drag. Both of these terms describe the force that opposes an object's motion through the fluid medium.
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.
What force opposes motion in fluids?
Viscosity is the force that opposes motion in fluids. It is a measure of a fluid's resistance to flow, and it arises due to internal friction between the molecules within the fluid.
Why the vehicles carrying inflammable fluid drag a chain along the ground?
Vehicles carrying inflammable fluids often drag a chain along the ground to dissipate static electricity that could build up during travel. This helps prevent sparks that could potentially ignite the flammable fluids, reducing the risk of fire or explosion.

When did Drag Race Eliminator happen?
Drag Race Eliminator happened in 1986.
When did Drag Racer - video game - happen?
Drag Racer - video game - happened in 2003.
What is streamling?
the science of shaping objects to reduce drag so that fluids flow more easily around them
Do fluids have friction?
Fluids have Friction. Everything in it, is under the force of fluid friction or drag. For example, a boat stops itself when the rowing stops, etc. Adarsh Kumar Dash
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 air and water resistance are both sometimes called?
Air resistance is also known as drag, while water resistance is often referred to as drag or hydrodynamic drag. Both of these terms describe the force that opposes an object's motion through the fluid medium.
If you are driving and there are no fluids in the car what will happen?
No fluids? Like gas? Well, you can probably run on fumes for a bit then the car will stop. I mean fluids like oil and antifreeze. Not gas, I know what will happen if you do not have gas. The person working on my car returned it to me with out oil etc.
What is the word that means to pull with force and that only has four letter?
Drag?
