Drag force is the resistance to motion of the object offered by the medium through which it travels, its value depends on the viscosity of the medium, and the shape, size and surface texture of the object.
Note: for any given object, the drag force is equal to the square of the velocity
* the drag coefficient of the object (rolling resistance is extra in the case of cars etc.)

What factors affect the drag force that acts on high speed train?
Factors affecting drag force on a high-speed train include shape/design of the train, speed of the train, air density, cross-sectional area exposed to the airflow, and surface roughness of the train. Additionally, factors like temperature and humidity can also influence drag force.
What is frictional resistance due to motion through air?
Frictional resistance due to motion through air is the force that opposes the movement of an object through the air. It is caused by air particles colliding with the surface of the object, creating a drag force that slows down the object's motion. The amount of frictional resistance depends on factors like the object's shape, speed, and the viscosity of the air.
What factors affect the drag force that acts on a high speed train?
The main factors that affect the drag force on a high-speed train include the train's speed, shape and design of the train, surface roughness of the train's exterior, and the air density through which the train is moving. Additionally, environmental conditions such as wind speed and direction can also impact the drag force.
What is the formula for aerodynamic drag?
The formula for aerodynamic drag is given by: drag force = 0.5 * drag coefficient * air density * velocity^2 * reference area. It represents the resistance encountered by an object moving through a fluid like air, with factors such as velocity, air density, drag coefficient, and reference area influencing the drag force.
What force that slow something down under water?
Drag force slows objects down underwater. This force is caused by the resistance of the water as an object moves through it. Factors such as shape, size, and speed of the object can affect the amount of drag force experienced.

What two factors does pressure depend on?
The two factors pressure depends on is force and area.
What happens when a solid object goes through a fluid?
When a solid object moves through a fluid, it experiences resistance due to the fluid's viscosity. This resistance generates drag force, which can slow down the object's motion. The magnitude of the drag force depends on factors like the object's shape, size, and speed, as well as the properties of the fluid.
What is the force excerted by a fluid on an object moving through the fluid?
The force exerted by a fluid on an object moving through it is called drag force. This force acts opposite to the direction of the object's motion and increases with the speed of the object. It depends on various factors like the object's shape, size, and speed relative to the fluid.
The SI unit of the drag force?

What is the force of water pushing against you as you move through it?
The force of water pushing against you as you move through it is called drag force. It depends on factors like your speed, the water's density, and your surface area in contact with the water. It increases as your speed or surface area increases.
