Converting dt graph (and table) to velocity/time using two point

Click For Summary
To convert a distance/time graph into a velocity/time graph using the two-point method, one must understand that velocity is the rate of change of displacement over time, represented by the slope of the distance-time graph. A straight line on the distance-time graph indicates constant velocity, resulting in a horizontal line on the velocity-time graph. Conversely, a parabolic distance-time graph indicates changing velocity, leading to a sloped velocity-time graph. It is crucial to grasp the physical significance of these relationships rather than just memorizing equations. Understanding these concepts will facilitate the conversion process effectively.

How can we convert a distance/time graph (that also contains a table of info) into velocity/time, using the two point method?

What is the relationship between "velocity" and "distance"?

'd' is displacement 've
you'll learn it afterward perhaps i see

i am giving you graph of speed vs time

if d-t graph is straight line at an angle α with x-axis then v-t graph is a line parallel to x axis
if d-t graph is parabolic then v-t graph is straight line at an angle θ with x axis

Not quite.

You need to know that velocity is the time rate of change of displacement/position. In graph form, it corresponds to the slope at a given point in the displacement-time graph.

You should have enough here to answer the question.

Note that you need to know the physical meaning of all of this. It is not enough to just know/memorize the equation without understanding what it means.

Thread 'Mousetrap Car Energy efficiency'

For simple comparison, I think the same thought process can be followed as a block slides down a hill, - for block down hill, simple starting PE of mgh to final max KE 0.5mv^2 - comparing PE1 to max KE2 would result in finding the work friction did through the process. efficiency is just 100*KE2/PE1. If a mousetrap car travels along a flat surface, a starting PE of 0.5 k th^2 can be measured and maximum velocity of the car can also be measured. If energy efficiency is defined by...
