On a distance time graph, velocity is measured as the gradient of the line. This is also the rate of change of the distance (if this question leads to calculus).
So a velocity of zero is shown by a horizontal line (if linear) or by a turning point (in a non-linear graph)

∙ 12y agoIn theory, yes, if an object is static it's velocity is zero. In practice, however, velocity of an object can only truly be determined in relation to at least one other object, so if only two objects are taken into account, there is no way to determine which one is moving and which one is static (or if they are moving in parallel, if both are moving, but at different speeds).
When you start considering larger groups of objects (up to and including the entire universe itself) it would be impossible to find out from within the system whether or not the entire system is moving.
Short version - yes, velocity can be zero, but it's impossible to tell for sure.

How do you figure out the starting point of a distance vs time graph when given the velocity vs time graph and a function?
it starts from zero.....
Will the graph of instantaneous velocity versus time have a Y-axis intercept of zero?
If you started at zero velocity, yes.
How Can you tell from a velocity-time graph that the velocity is constant?
velocity is nothing but speed of a body in the given direction. suppose if body is moving with constant velocity then VT graph will be parallel to the X -axis, if not then the VT graph is not parallel to the X-axis it means then object is moving with different velocity or it has its dierection or both velocity and aswell as direction.
What does a horizontal line on a velocity time graph show for acceleration?
Any curved line will indicate a change in acceleration. Straight lines with slope indicate a steady velocity and straight lines with zero slope indicate a lack of motion.If the X axis (left to right) is for time and the Y axis (up and down) is for speed, it would curve up.
What is the mathematical model for a velocity vs time graph?
Final position=zero position + Velocity at zero*final time + 0.5*acceleration*time^2
What does a zero velocity graph look like?
In a velocity-time graph it will be the time axis (where velocity = 0). On a distance-time graph it will be a line parallel to the time axis: distance = some constant (which may be 0).
How do you know there is no motion on a distance time-graph?
distance = velocity x time so on the graph velocity is slope. If slope is zero (horizontal line) there is no motion
What is the slope in the distance time graph when the body is at rest?
the slope of distance time graph gives us velocity but when the body is at rest it will be zero
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.
How do you figure out the starting point of a distance vs time graph when given the velocity vs time graph and a function?
it starts from zero.....
What does a horizontal line on a distance-time graph indicate?
It means there is no velocity - it is at rest and nothing is moving. The slope of the line is velocity - a horizontal line is zero slope = zero velocity
Which physical quantity is calculated by the slope of distance time graph?
The radial velocity ie velocity towards or away from your starting point. It is NOT the ordinary speed or velocity because you can run in a circle around your starting point at top speed but the distance will not change so the slope of the distance time graph will be zero.
Will the graph of instantaneous velocity versus time have a Y-axis intercept of zero?
If you started at zero velocity, yes.
What does the slope of a line on a distance-versus-time graph show?
It shows the speed of an object in a direction towards or away from the reference point. This is not the speed of the object because any motion in a transverse direction is ignored. For example, even if a racing car is going at top speed around the reference point on a circular track, the distance v time graph will be a horizontal line. The slope will be zero.
What type of motion is occurring when the slope of a position versus time graph is constant?
The slope of [distance vs. time] is [speed]. If the slope is constant, then the speed is constant,meaning the magnitude of acceleration is zero.(The direction of velocity might still be changing though, which wouldn't show up on the graph.)
Does a horizontal line on a distance time graph show constant speed?
No. It shows zero speed. Velocity is distance/unit time. The slope of the line shows change in distance / change in time. Since distance never changes as time changes, the change in distance is zero. Alternatively, the slope of a horizontal line is zero. If zero speed is considered "constant", then yes, it does show constant speed but the speed is zero.
When d-t graph is parallel to time axis what can you say about the motion?
For that period of time, d(t) (the distance) is not changing so the motion is zero velocity.
