The velocity at a stationary boundary is zero because the boundary is not moving, thus preventing the fluid from moving past it. This creates a no-slip condition where the fluid particles in direct contact with the boundary stick to it and do not move. This stagnant layer of fluid at the boundary sets the velocity at zero.
What else can I help you with?
Zero velocity is also called?
Zero velocity is also called stationary or at rest.
Does a stationary object have momentum?
No, a stationary object does not have momentum because momentum is the product of an object's mass and its velocity. If an object is not moving (velocity is zero), then its momentum will also be zero.
If object is stationary is its accelaration necessarily zero?
Yes, if an object is stationary, its acceleration is zero because acceleration is the rate of change of velocity over time. When an object is not moving, its velocity is constant and therefore there is no change in velocity, resulting in zero acceleration.
Does a stationary object has interia and momentum?
Yes, a stationary object still possesses inertia, which is its resistance to changes in motion. However, since momentum is dependent on an object's mass and velocity, a stationary object has zero momentum.
How is velocity of zero different from an accerlation at zero?
Velocity at zero means the object is not moving, while acceleration at zero means the object is moving at a constant velocity. Velocity at zero can be motionless or stationary, while acceleration at zero indicates that there is no change in velocity, even if the object is moving.
Zero velocity is also called?
Zero velocity is also called stationary or at rest.
Zero velocity means vehicle must be stationary?
Zero velocity means that the vehicle and the person who is measuring the velocity are moving together.
Does a stationary object have momentum?
No, a stationary object does not have momentum because momentum is the product of an object's mass and its velocity. If an object is not moving (velocity is zero), then its momentum will also be zero.
What is an object that's not moving?
A stationary object with velocity of zero.
If object is stationary is its accelaration necessarily zero?
Yes, if an object is stationary, its acceleration is zero because acceleration is the rate of change of velocity over time. When an object is not moving, its velocity is constant and therefore there is no change in velocity, resulting in zero acceleration.
What causes no-slip condition?
consider boundary layer over any body.... fact is that they have surface velocity as zero this cause no slip condition.... so that any body over the surface of them will not slip when they are moving in stream of fluild.. eg we see in earth boundary layer over the earth does not allow one to slip from one place to another during jumping.
Does a stationary object has interia and momentum?
Yes, a stationary object still possesses inertia, which is its resistance to changes in motion. However, since momentum is dependent on an object's mass and velocity, a stationary object has zero momentum.
How is velocity of zero different from an accerlation at zero?
Velocity at zero means the object is not moving, while acceleration at zero means the object is moving at a constant velocity. Velocity at zero can be motionless or stationary, while acceleration at zero indicates that there is no change in velocity, even if the object is moving.
Can stationary have non zero angular acceleration?
No, an object is considered stationary when it has zero velocity and zero acceleration. Angular acceleration refers to the rate at which an object's angular velocity changes over time. If something has a non-zero angular acceleration, it means that it is rotating at a changing rate.
Can you tell from a velocity-time graph whether an object is stationary?
If the curve is horizontal, then the speed is constant. If that horizontal graph lies on the x-axis, then the constant speed is zero, and the object is stationary.
How much momentum does a stationary 5500kg mass have?
A stationary object has zero momentum since momentum is the product of an object's mass and its velocity. In this case, since the object is not moving, its momentum is zero.
The net force acting on an stationary object is zero Which best describes the object's velocity?
If the net force acting on a stationary object is zero, then the object's velocity will remain unchanged, meaning that the object will stay stationary. In other words, the object will not start moving or accelerate without an external force acting on it.
