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)

In 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.

Velocity is zero on a distance-time graph at the points where the graph is horizontal (flat) because the distance is not changing. This occurs when the object is at rest or changes direction.

How do you figure out the starting point of a distance vs time graph when given the velocity vs time graph and a function?

To find the starting point of a distance vs time graph from a velocity vs time graph and a function, you would integrate the velocity function to find the displacement function. The starting point of the distance vs time graph corresponds to the initial displacement obtained from the displaced function.


Will the graph of instantaneous velocity versus time have a Y-axis intercept of zero?

Not necessarily. The graph of instantaneous velocity versus time may or may not have a Y-axis intercept of zero. It depends on the initial conditions and motion of the object. If the object starts from rest, then the initial velocity is zero, and the graph will have a Y-axis intercept at zero.


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.


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.


Does the horizontal line on the velocity vs time graph indicate a constant and positive acceleration?

No, a horizontal line on a velocity vs. time graph indicates a constant velocity, not acceleration. An acceleration would be represented by a non-zero slope on a velocity vs. time graph.
