Can constant velocity be zero?
Yes. Zero velocity is a velocity; if it is always zero then it is a constant velocity.
Is it possible for an object to have zero velocity?
Zero relative velocity to another object, sure no problem. Zero absolute velocity, not possible as there is no absolute reference to compare to.
What is the condition of the position-time graph when the velocity-time graph passes through zero?
As, in the velocity-time graph, curves passes through zero means 'when time is zero velocity is zero'. Velocity is time derivative of displacement. So displacement is maximum or minimum when time is zero in position-time graph.
What is your acceleration if you have a constant velocity?
If your velocity is constant, then your acceleration is zero.
If a small marble is dropped straight downward what is the initial velocity of the marble?
The initial velocity is zero. In most basic physics problems like this one the initial velocity will be zero as a rule of thumb: the initial velocity is always zero, unless otherwise stated, or this is what you are solving for Cases where the initial velocity is not zero examples a cannon ball is shot out of a cannon at 50 mph a ball is thrown from at a speed of 15 mph etc
If displacement is not changing as a function of time then what can we say about velocity?
If the displacement is not changing, the velocity is zero.
Can constant velocity be zero?
Yes. Zero velocity is a velocity; if it is always zero then it is a constant velocity.
What is a velocity potential?
A velocity potential is a scalar function whose gradient is equal to the velocity of the fluid at that point. If a fluid is incompressible and has zero viscosity (an ideal fluid) its velocity as a function of position can always be described by a velocity potential. For a real fluid this is not generally possible.
Can an object be moving when its acceleration is zero?
Acceleration, which is the change of velocity over the change in time, will equal zero when there is no change in velocity. This can occur when an object is stationary or when an object is traveling at a constant velocity.
What is another word for zero velocity?
Zero velocity = No acceleration
Is the net force acting on a body is zero will the velocity be zero?
No, The velocity CHANGE will be zero
What is the velocity if acceleration is zero?
velocity may be zero or may not be zero i.e. if the object may continue to move with uniform velocity.
What is the acceleration if velocity is zero?
velocity may be zero or may not be zero i.e. if the object may continue to move with uniform velocity.
How is velocity of zero different from an accerlation at zero?
Acceleration is changing velocity. Zero velocity means no motion. Zero acceleration means constant, unchanging motion.
Zero acceleration will the velocity be constant?
Whenever velocity is constant, the acceleration is zero. This also works when the velocity is zero, the acceleration is zero. That pretty much means the object isn't moving. But, yes/ If velocity is constant, accleration is zero.
Can an object accelerate and have zero velocity?
I'm not a scientist, but the following seems reasonable to me. If your frame of reference is the earth's surface, then it seems clear that an object can have zero velocity and zero acceleration. You could even have non-zero velocity and zero acceleration. What seems impossible is to have zero velocity and non-zero acceleration. When you think of accelaration think of changing velocity. A car moving straight down the highway at a constant speed of 55 mph is neither speeding up nor slowing down. Though it has velocity, there is no change in its velocity so acceleration will be zero. For a car parked on the side of the road, on the other hand, its velocity will be zero but what about its acceleration? Is velocity changing? No, so it will have zero velocity and zero acceleration.Yes.
Can you have a zero acceleration but non zero velocity explain it with help of a graph?
Yes, you can. Zero acceleration simply means there is no CHANGE in velocity. It doesn't mean there is no velocity.
