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 displacement is not changing as a function of time, then velocity is zero. Velocity is the rate of change of displacement with respect to time, so if there is no change in displacement, 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.
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.
Is the net force acting on a body is zero will the velocity be zero?
Not necessarily. If the net force acting on a body is zero, the body's velocity will remain constant (assuming no other forces act on it to change its velocity), but it doesn't mean the velocity will be zero. If the initial velocity is zero, then the velocity will remain zero if the net force is zero.
Can particle have zero speed and non zero velocity?
No, a particle cannot have zero speed and non-zero velocity simultaneously. Speed is the magnitude of velocity and if speed is zero, then velocity must also be zero.
When the acceleration is zero what can you say about the velocity of an object?
When acceleration is zero, the object's velocity can still be changing if the initial velocity is not zero. However, if acceleration is zero and the initial velocity is also zero, then the object's velocity will remain constant.
What is the momentum of zero?
The momentum of an object with zero velocity is zero. Momentum is calculated as mass multiplied by velocity, so if velocity is zero, momentum will also be zero.
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.
What is another word for zero velocity?
Zero velocity = No acceleration
At what points does velocity change direction?
Velocity changes direction at points where it reaches zero, meaning it goes from moving in one direction to moving in the opposite direction. These points are called the turning points, or points of inflection, in the velocity function.
Can you have a zero acceleration but non zero velocity explain it with help of a graph?
Yes, it is possible to have zero acceleration with a non-zero velocity. This occurs when the velocity is constant. On a velocity-time graph, a flat, horizontal line represents constant velocity, while a zero slope (flat line) represents zero acceleration.
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.
