1613560396267.png

now there is something i am not getting here, consider for instance graph ##a##,
analyzing this graph i can say as follows;
between time ##0≤ t<1, ## the velocity is increasing...
at time ##t=1##, also reffered to as being intantaneously at rest, at this point we have acceleration ##a=0##,
between time##1< t<3 ##, the velocity is decreasing...
at the point ##t=3##, we have ##a=0##,
between time ##3< t<5 ##,velocity is increasing...

is my analysis correct?

lets start with the graph a. Now if my analysis is correct, which corresponding graph will suffice?
i would expect that if velocity is increasing between time ##0≤ t<1,## then acceleration should equally be increasing, and i cannot see which graph reflects that...

I propose you reconsider:
(1) the position ##x## is increasing, but it is going at a lower and lower rate. What does that say about the velocity, which is the rate of change of the position ?

(2) "at rest" says what about the velocity ?

to answer part ##(2)##, at rest, literally means that the velocity at that point ##=0##, i am still trying to figure out part##(1)##. I still do not understand what you mean by lower and lower rate. The rate that you are 'reffering' to can simply be called velocity. The velocity i.e the gradient value is positive at that particular interval that i mentioned, hence use of my term increasing...

ok, i can see that from
x= 34.14.243
t=0.40.81.21.62

ok Bvu sir, i can see that the rate of change i.e velocity is reducing i.e ##[7.5, 5.125, 3.5, 2.5, 1.5]## m/s...

approah 2
consider the velocity time graph ##e##, at time ##t=0## and ##t=1## the graph at this points are represented by a straight line, therefore the distance traveled betwen these two points, ##x= 0.5 ×1×10= 5m## which corresponds only with distance- time graph ##(a)## having co ordinates ##(x,t)=(1,5)##.
am i right? therefore for this case, ##a→e##

Note textbook answer are ##[a→e, b→f, c→d]##

Dear Chwala,

This is an exercise in differentiation and integration, both very important for physics.

Differentiation

You know that the rate of change in position is the velocity: ##v = \displaystyle {\Delta x\over \Delta t} ##

When things change continuously, this becomes a differential (instantaneous velocity):$$v(t) ={dx(t)\over dt}$$
This brings you from graphs of ##\ x(t)\ ## to graphs of ##\ v(t)\ ## because ##\ \displaystyle {dx(t)\over dt} ## is the slope of the ##x(t)## graph at time ##t##. You take a transparent ruler and look for tangents.
For example in figure a) the interesting ones are:

1613650062294.png

(sorry for the quality :wink: )
  • at ##t=0## the yellow line with a slope of 10 m/s.
  • at ##t=1## and ##t=3## the orange lines with slope 0 ##\Rightarrow\ v(t)=0## m/s.
  • and, finally and very interesting: at ##t=2## you have an inflexion point wth slope -1 m/s.
Inflection points are very helpful: at such a point the curve changes from convex to concave (or vice versa), so the slope is at a minimum (or maximum).​
With these four characterizing points it is very easy to pick the right ##\ v(t)\ ## graph !Integration

From $$v(t) ={dx(t)\over dt}$$ we go to (mathematicians won't like this, but we do :smile: it without hesitation) $$
v \Delta t =\Delta x\quad\Rightarrow\quad dx(t) = v(t) dt \quad\Rightarrow\quad x-x_0 = \int dx(t) =\int v(t) dt$$And this brings you from graphs of ##v(t)## to graphs of ##x(t)##.

The dotted items for integration in reverse: [edit:sorry, mistake in first edition :frown: ]

The dotted items used for differentiation we reverse for integration :
  • the y-axis crosssings give you extrema: ##v(t) = ## zero
  • Extrema give you inflexion points
What you don't get is ##x_0## : the constant of integration can not be found from the integrand ##v(t)##.​
So in that respect integration deserves a bit more attention than differentiation. You may need to draw a line with a given slope but unknown intercept at some point(s). The most logical candidate is at ##t=0##.

As an example I could do this for figure e) but by now we know where that leads us, don't we ?
Instead, why don't you try figure d) in this manner to see if I have actually been helpful in this.

(It is a great pity you already have the answers, it distorts unbiased thinking).##\ ##

Thanks for your time on this,...looks like it requires some indepth thinking...I guess differentiation would be easier than integration going by what I see from your approach nevertheless I will take your advise, form the tangents and see whether I could get the ##x## function ...

[edit] I forgot one that doesn't appear in this exercise. So, for completeness:
  • In differentiation a straight section means a constant derivative
  • When integrating vice versa
(One can partially link this to the inflexion point where the derivative is "instantaneously constant")

i want to understand the graph 3.e ...ok i want to get this right, so in integration i should be using the constant derivative to get the straight section(distance function) right? by considering the points ##(0,0)## and ##(0.8,2)## i am getting a gradient of ##2.5##, is this correct...therefore is this the value that i am integrating?

I tried to make clear to you that you can not obtain ##x_0## from a ##v(t)## plot, because constants disappear when differentiating. So the best you can get is ##\Delta x##.

You now treat the first second of (e) as a straight line, which is ok, but clearly an approximation.

o:) [edit sorry: ##x = 0## does not mean crosssing the y-axis --- Why not start with finding the y-axis crossings]

Why not start with finding the time-axis crossings of the ##v(t)## plot -- they provide the moments when the plot of ##x(t)## is horizontal. Namely at ##t-1## s and ##t= 3## s (orange points in the picture below).

At ##t=1## s ##v ## changes from positive (forward) to negative (backward), so that is a maximum in the ##x(t)## plot.
At ##t=3## s (a little more actually), ##v ## changes from negative (backward) to positive (forward), which means that's a minimum in the ##x(t)## plot.

Then the next easy one is the minimum in ##v(t)## at ##t = 2## s (red) : an inflexion point in the ##x(t)## plot.

If these three are not enough to identify the corresponding ##x(t)## plot, you can still make a decisive distinction with the ##v(0) = 10## (left yellow point)which is the slope of the ##x(t)## plot at ##t=0##, thereby discarding possibilities (b) and (c)

thanks bvu, phew! sweating here, so basically you are implying that we can look at the behaviour of the gradients on the v-t graph to realize the corresponding maxima and minima points on the distance -time graph and generally come to some deduction...i think i am a bit confused here because the approach that i had was by considering the rate of change on the v-t graph being accelaration function...

In (f) you also have ##\ v=0\ ## at ##\ t=0\ ##, so the ##\ x(t)\ ## plot must take off horizontally. However, this does not help to distinguish between (b) and (c) , because both start the same way.

Furthermore: on (f) at ##t=1## you can conclude there must be an inflexion point in the ##x(t) \ ## graph. This does distinguish between (b) and (c) .

1. Considering the ##x−t## graph, at ##t=3,## velocity =##0m/s## agreeing with the ##v−t## graph.
2. I also tried drawing a tangent line on the ##x-t##graph at the point ##t=4##, ...there is a problem here, the values are not in sync...i am getting ##v(t)=10m/s## but correct value is ##v(t)=14m/s##
3. Analyzing the v−t graph, we have a stationary point at ##t=2## which implies an inflection on the ##x−t## graph
4. At the point ##t=2## to ##t=4## on the ##v-t## graph the graph changes from negative to positive, this implies a minimum point on the ##x−t## graph.

I think we have milked out the graphical stuff quite well and quite satisfactory by now. So I want to do something in another direction. Usually I tell posters to make a sketch if all I see is symbols and equations. This time it's all graphs and now I have a small challenge:

No, I really meant

Find the equation for ##\ x(t)\ ##, given that the equation for ##\ v(t) \ ## is $$v(t) = 3.66 \,t \, (t-2) \ .$$As you correctly observe, you need one initial condition. Let that be ##\ x(0) = x_0\ ## with ##\ x_0 = 0 ## m.
 
  • #31
then this should be easy,
##v(t)= 3t^2-6t##
##x(t)=∫vdt##
##x(t)=t^3-3t^2+k##
with condition, ##x(t=0.4)=0##
we have, ##x(t)=t^3-3t^2+0.416## as the required equation.

The idea was that you would NOT look at any graphs, but simply do the integration. And indeed:

Is perfect!
And, to top if off with a picture as prize: the graph looks exactly like figure (b) :partytime::partytime::partytime::

Thank you Bvu, i am assuming you are a Professor...you have great insight...thank you sir. I have learned on the behaviour of functions and their derivatives (considering the fact that the equation of the function has not been given) particularly on the aspect of moving from negative to positive for eg considering a function which implies the converse i.e positive-negative when it comes to its derived function. I also learned something on inflection points implying either a maximum or a minima on corresponding given functions.

1. What is the purpose of finding the corresponding graphs for distance-time graphs?

The purpose of finding the corresponding graphs for distance-time graphs is to represent the relationship between distance and time in a visual form. This can help in understanding the motion of an object and analyzing its speed and direction.

2. How do you find the corresponding graphs for distance-time graphs?

To find the corresponding graphs for distance-time graphs, you need to plot the distance values on the y-axis and the time values on the x-axis. This will create a line graph, where the slope of the line represents the speed of the object.

3. What do the different shapes of the corresponding graphs indicate?

The shape of the corresponding graphs can indicate the type of motion of the object. A straight line represents constant speed, a curved line represents changing speed, and a horizontal line represents no motion.

4. Can the corresponding graphs be used to calculate the distance traveled?

Yes, the corresponding graphs can be used to calculate the distance traveled by finding the area under the graph. This can be done by dividing the graph into smaller shapes, such as rectangles or triangles, and then calculating the area of each shape and adding them together.

5. How can the corresponding graphs be used to predict future motion?

The corresponding graphs can be used to predict future motion by analyzing the trend of the graph. If the graph shows a constant slope, it indicates that the object will continue to move at a constant speed. If the slope is changing, it indicates that the object's speed will also change in the future.
