The gradient of the tangent to the graph at the instant in question.
The line on a position-time graph represents velocity.
By calculating the slope at different or deisired points on the position-time graph by drawing tangents at the points. Since, slopes on a position-time graph represent velocity, you now have the velocity of the object at the time on which you have drawn the tangents. Now, that you have the velocity and you already had the time, all you have to is sketch the velocity-time graph Remember Slope (velocity on position-time graph)= 'd2-d1' divided by 't2-t1'
The Average Velocity on a position time graph or a velocity time graph.
The slope of a position-time graph is velocity. The slope of a velocity-time graph is acceleration. Displacement also can be determined by determining the area under the slope of a velocity-time graph.
Simply put, a velocity time graph is velocity (m/s) in the Y coordinate and time (s) in the X and a position time graph is distance (m) in the Y coordinate and time (s) in the X if you where to find the slope of a tangent on a distance time graph, it would give you the velocity whereas the slope on a velocity time graph would give you the acceleration.
The velocity position time graph is rightward. This can change at anytime.
A position time graph can show you velocity. As time changes, so does position, and the velocity of the object can be determined. For a speed time graph, you can derive acceleration. As time changes, so does velocity, and the acceleration of the object can be determined.If you are plotting velocity (speed) versus time, the slope is the acceleration.
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 to calculate displacement on a velocity time graph
If an x-t graph is a position-time graph, velocity is the slope of the line on the graph.
You can't, since the slope of the graph means average velocity and the area of the graph has no meaning. The only way to find instantaneous velocity from position-time gragh is by plugging the data into the kinematic equations to get the answer. Edit: Actually you can if you take the derivative of the equation of the curve it will give you the equation of the velocity curve
