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.

If the object is not stationary, then the graph must depart from zero.
Yes, the object is stationary when the velocity is zero, the point or points where the graph crosses the horizontal time axis

∙ 9y agoWell, it's hard to graph a velocity-time graph in the first place, since velocity is a vector. I assume you mean speed-time graph. In that case, when you are moving faster, the velocity will simply be higher up in the graph.
If the velocity-time graph is a horizontal line, then the velocity is constant. This means that the object is moving at the same speed in a straight line without changing its velocity.

∙ 12y agoThe velocity has changed from positive to negative, or vice-versa.

∙ 8y agoif the velocity is positive to start with it changes direction when the velocity is less than zero; that is, when it is negative.

Why does the y-value of the velocity vs. time graph stay constant?
If the y-value of the velocity vs. time graph stays constant, it means the object is moving at a constant velocity, meaning there is no change in speed or direction over time. This could occur if there is no net force acting on the object, resulting in a balanced situation where the velocity remains constant.
Does a velocity graph tell you where to start?
No, a velocity graph does not indicate where to start. It provides information about the speed and direction of an object's motion at different points in time but does not specify the initial position of the object.
When velocity is changing what is happening to the slope on a position versus time graph?
When velocity is changing, the slope of the position versus time graph represents the velocity at that particular moment. The slope becomes steeper when velocity is increasing and shallower when velocity is decreasing. A horizontal line indicates zero velocity.
What is the position time graph corresponding to this situation?
The position-time graph for a person walking away from a starting point at a constant speed would be a straight line with a positive slope indicating a constant increase in position over time.
How can I tell when two objects have the same velocity on a position graph?
When two objects have the same velocity on a position graph, their position vs. time graphs will have parallel lines with the same slope. This indicates that both objects are covering the same distance in the same amount of time, resulting in the same velocity.
Why does the y-value of the velocity vs. time graph stay constant?
If the y-value of the velocity vs. time graph stays constant, it means the object is moving at a constant velocity, meaning there is no change in speed or direction over time. This could occur if there is no net force acting on the object, resulting in a balanced situation where the velocity remains constant.
Can you tell from a velocity-time graph whether an object is stationary?
Yes, if the velocity-time graph shows a horizontal line at zero velocity, then the object is stationary. This would indicate that the object is not moving.
What does a curved line on a distance versus time graph tell you?
It tells you that the velocity of the body is not constant. There is acceleration or deceleration.
What do x-t graphs look like for constant velocity?
The x-t graph can't tell you anything about direction, so you can only make observations regarding speed, not velocity. For constant speed, the x-t graph is a straight line. The slope of the line is numerically equal to the constant speed.
If a graph shows time on the horizonal axis and speed on the vertical axis a straight horizontal line across the graph would indicate?
The straight horizontal line would indicate constant speed.(NOT constant velocity. The velocity could very well be changing, but the graphdoesn't tell you anything about the direction of the motion, only that the speedis constant.)
What does the slope of the line on a distance-time graph tell you?
velocity
Does a velocity graph tell you where to start?
No, a velocity graph does not indicate where to start. It provides information about the speed and direction of an object's motion at different points in time but does not specify the initial position of the object.
What does the slope of the tangent to the curve on a velocity-time graph measure?
The slope of the tangent to the curve on a velocity-time graph represents the acceleration of an object. Positive slope indicates acceleration in the positive direction, negative slope indicates acceleration in the negative direction, and zero slope indicates constant velocity.
What one thing does a velocity-time graph not tell you about your object that a position-time graph does?
Distance covered at a given time.
How do you tell whether a graph shows a constant or variable rate of change?
The slope of each point on the line on the graph is the rate of change at that point. If the graph is a straight line, then its slope is constant. If the graph is a curved line, then its slope changes.
What does a velocity-time graph tell us?
How the speed of something changes over time.
Is it possible to tell the difference between moving at a constant velocity and not moving at all?
Yes, it is possible. If you are moving at a constant velocity, you will feel no acceleration or deceleration. In contrast, if you are not moving at all, you will feel stationary with no change in velocity.
