Is velocity-time graph under?
The area under a velocity-time graph is the displacement. Velocity can be negative if an object is moving backwards. The displacement can also be negative. An area beneath the x-axis has a negative value.
Can a velocity-time graph be negative?
Speed is always positive, while velocity can be negative. The speed/time graph would be the absolute value of the velocity/time graph.
Can velocity-time graph be perpendicular to axis?
If velocity-time graph is perpendicular to the time axis, that means at a particular time the velocity of a body is continuously increasing that is not possible. Hence, a v-t graph can not be perpendicular to the time axis.
Can a distance time graph go down?
On a distance-time graph, there are no line sloping downwards. A moving object is always ‘increasing’ its total length moved with time. ‘Curved lines’ on a distance time graph indicate that the speed is changing. The object is either getting faster = ‘accelerating’ or slowing down = ‘decelerating’.
How do you represent a velocity-time graph?
A horizontal line on a speed-time graph represents a constant speed. A sloping line on a speed-time graph represents an acceleration. The sloping line shows that the speed of the object is changing. The object is either speeding up or slowing down.
What is velocity-time graph in physics?
A velocity-time graph shows the speed and direction an object travels over a specific period of time. Velocity-time graphs are also called speed-time graphs. The vertical axis of a velocity-time graph is the velocity of the object. The horizontal axis is the time from the start.
How do you tell if velocity is increasing or decreasing on a graph?
In a velocity-time graph, acceleration is represented by the slope, or steepness, of the graph line. If the line slopes upward, like the line between 0 and 4 seconds in the Figure above, velocity is increasing, so acceleration is positive.
What does velocity-time graph represent?
A velocity-time graph shows changes in velocity of a moving object over time. The slope of a velocity-time graph represents acceleration of the moving object.
Can position time graph be ever perpendicular to time axis?
The distance-time graph of a moving body as straight line perpendicular to time axis is not possible as it represents different values of distance travelled at a particular time which is not possible.
What would be acceleration of a body if its velocity time graph is a line parallel to the time axis *?
When velocity time graph is parallel to time axis, velocity = constant, i.e., acceleration of body is zero.
What does it mean when a distance time graph goes down?
A diagonal line going up in a distance-time graph means that the object is at a constant speeed. A diagonal line going down means that the objects speed is decreasing.
Can distance time graphs have a negative slope?
We can describe how an object moves with time by drawing a distance-time graph. By the way – if the line is going downwards (a negative slope or gradient), then the object is still moving at a constant speed, but in the reverse direction (back to its starting point).
