The gradient of the tangent at that point, or if you know the equation of the line, the differential of the equation at that point..
This is similar but It is simpler:
Step 1 -- From the distance-time graph, if you know what time you are particularly in, go to your time axis (should be the horizontal axis) and from this particular time (point) on the time axis, go vertically upwards until it intersects the graph. Step 2 -- At this point of intersection, go horizontally to the left and read the value of the point at which this horizontal line intersects the vertical axis. This is the distance travelled by the body/particle at the particular instant chosen. Step 3 -- To determine the instantaneous velocity, simply divide the distance (determined in Step 2) by the time (from Step 1).
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'
calculate distance from area under graph between equal time intervals
ie 0-1 secs , 1-2 secs
if v/t graph is mathematical curve, then use integration , if not then estimate.-1.286 - -1
By getting the displacements S1 at time t1 and S2 at time t2, now we use the expression S2 - S1 / t2 - t1. This gives the average velocity in the duration of time from t1 to t2.
Instantaneous velocity is got by finding the slope of the tangent drawn to the curve at that instant of time.
If time is the x-axis, and velocity is the y-axis, then find the specific time you want to know, then determine on the graph the velocity for that specific point in time, and that is the instantaneous velocity.
Besides obviously distance at any instant, on a connected, continuous distance-time graph, you can obtain instantaneous velocity and instantaneous acceleration.
To obtain the average velocity from a displacement-time graph, you can calculate the slope of the line connecting two points on the graph. Divide the change in displacement by the change in time. To obtain the instantaneous velocity, you need to find the slope of the tangent line at a specific point on the graph. Choose a point on the graph and draw a line tangent to the curve at that point. The slope of this tangent line will give you the instantaneous velocity at that specific point.
You cannot because a displacement-time graph is concerned only with radial motion: displacement from a fixed point of reference. Any transverse motion is completely ignored. Thus, if you had a body going around in a circle about the point of reference, its speed would be recorded zero!
Kinetic energy is given by mv2, where m is mass and v is speed. To obtain a result let me divide the new kinetic energy, m(v/2)2 (where the initial velocity is divided by two), by the initial velocity, mv2. (v2/4)/v2 = 1/4 The kinetic energy will be one fourth of what it was when the speed is halved.
I use an instrument called a "moving van anenometer" to measure velocity of the airflow in feet per minute. I take multiple readings at each register, average them, and multiply them by a percentage factor based on the "free area" of the register to obtain a volume reading in cubic feet per minute. Then I add up the CFM (cubic feet per minute) of each supply register in the room to determine the total air supply to that room.The HVAC Veteran

The average acceleration can be obtained by finding the slope of the graph. The instantaneous acceleration is found by drawing a tangent to a particular point on the graph (instant) and finding the slope of than tangent.

To obtain instantaneous speed you will need to utilize the formula v = speed multiplied by time if you have the speed already. If you do not have the speed use v = dx/dt.
Assuming t is time, you need to know the distance traveled in time t. Then, divide the distance by time to obtain speed (velocity).
Francium is very radioactive and very difficult to obtain; heating of francium due to the decay leads to instantaneous vaporization of francium.
-- Pick two points on the graph. -- Find the difference in time between the two points. -- Find the difference in displacement between the same two points. -- (Difference in displacement) divided by (difference in time) is the average Speed . You can't tell anything about velocity from the graph except its magnitude, because the graph displays no information regarding the direction of motion.
