Uniform flow cannot occur in a frictionless channel because the absence of friction does not allow for energy dissipation, causing the flow velocity to remain constant throughout the channel. In reality, energy is lost to friction, resulting in a non-uniform velocity profile.

What is frictionless in motion?

Frictionless motion describes a situation where there is no resistance or opposition to an object's movement. This can occur in idealized scenarios, such as in a vacuum or with certain lubricated surfaces, where friction is eliminated. In these cases, objects can continue moving indefinitely without the need for an external force to maintain their motion.


An example of uniform motion in a straight line in which velocity is changing at uniform rate?

An object moving along a straight line with increasing velocity in a uniform manner is an example of uniform motion with changing velocity at a uniform rate. This could occur if a car accelerates at a constant rate along a straight road.


What do you mean by uniform and non uniform magnetic fields?

A uniform magnetic field has the same strength and direction at all points in space. In contrast, a non-uniform magnetic field is one where the strength and/or direction varies from point to point. Uniform magnetic fields are often created in laboratory settings, while non-uniform magnetic fields can occur naturally or in more complex magnetic systems.


Which is better non uniform?

Choosing a non-uniform distribution can be better than a uniform distribution when the data closely follows real-world scenarios or when certain values are more likely to occur than others. Non-uniform distributions can provide a better representation of probability in many practical situations, allowing for more accurate modeling and analysis.


What is the definition of uniform retardation?

Uniform retardation refers to a constant decrease in velocity over time, resulting in a negative acceleration. This can occur in situations where a consistent force opposes the direction of motion, causing the object to slow down at a steady rate.

Is channel-mediated diffusion a form of active transport?

Yes, when channels are specific for the structures of individual molecules it is active transport. Active transport cannot occur if the energy they are moving is not of the same type, like glucose cannot move calcium.


When is friction necessary for some type of movement to occur?

If a ball slides down a frictionless hill there will be no rotation of the ball. But with friction the ball will both translate and rotate down the hill.
