The Average Velocity on a position time graph or a velocity time graph.
On a speed versus time graph, acceleration is represented by the line on the graph. If acceleration is constant, the line cuts through equally between the axis and starts from the zero point.
No, it is a straight line passing through the origin.
-- If the position/time graph is a straight line, then the speed is constant, and the slope of the line is the average speed, as well as the instantaneous speed at any moment. -- If the position/time graph is not a straight line, then the average speed between two moments in time is the slope of a straight line drawn between those two points on the graph.
Yes. Free fall can be graphed on a position-time graph and a velocity-time graph. Refer to the related link below for examples.
Initial position is got by the y-intercept
In such graphs the x-axis is usually (but not always) the time axis. The x-intercept represents the time(s) at which your position is at the starting point - either for the first time or later.
If time is the x-axis as expected then the x-intercept would be zero movement of the velocity.
It means that the object was travelling away from or towards the point of reference with a velocity represented by the intercept at the start of the measurement, that is, at time t = 0.
A position-time graph, is one in which position is plotted on the y-axis and the time is on the x-axis. A position-time graph is similar to a distance-time graph, but direction of motion in the y-axis.
The velocity of the object at time = 0
The velocity position time graph is rightward. This can change at anytime.
The starting speed.
No. Slope of position/time graph is speed, or magnitude of velocity.Slope of speed/time graph is magnitude of acceleration.
The area of a position-time graph does not have a meaning. However, the area under a velocity-time graph is the displacement. Refer to the related link below for an illustration.
