Motion Graph

Motion graphs can tell you how far a body has travelled, how fast it is moving and all the speed changes there have been.

Distance - time graph ( s-t graph )
Distance of a body from start point is measured. Here are 4 examples of the motion of a car represented by 4 s-t graph
Case 1 : A car is travelling at constant speed
s-t graph of Case 1
s-t graph of Case 2
Case 2 : A car is travelling with increasing velocity
Case 3 : A car is travelling with decreasing velocity
s-t graph of Case 3
s-t graph of Case 4
Case 4 : A car is at rest (stationary)

In a s-t graph, the velocity at any time is given by the slope of tangent to the graph at the instant. If the speed is uniform, the graph inclined straight line.

Speed - time graph ( v-t graph )
v-t graph gives the velocity of a moving object at different time. Here are 4 v-t graph representing the motion of 4 cars:
v-t graph of object moving at constant speed
v-t graph of object moving at uniform acceleration
v-t graph of object moving at uniform deceleration
v-t graph of object moving at non-uniform acceleration
The acceleration at any time is given by the slope of tangent to the graph at that time
The area enclosed by the graph between a certain time interval represent the displacement of the car travelled during that time interval.
How to analysis v-t graph?
Many students may get confused when they deal with the above graph. We are going to explain it region by region.
  • ab : Object increases its velocity from rest. (Acceleration)
  • bc : Object decreases its velocity to zero. (Deceleration)
  • cd: Object INCREASES its velocity from rest but it travel in REVERSE direction. (ACCELERATION)
  • de: Object DECREASES its velocity to zero and it travel in REVERSE direction. (DECELERATION)

Acceleration - time graph ( a-t graph )
The a-t graph gives the acceleration of a moving object at different times.
Here are 3 examples of a-t graph representing the motion of 3 different cars
Case 1 : From this graph, we know that the speed is increasing and the s-t graph should also be increasing with a concave downward shape.
a-t graph of case 1
Case 2 : From this graph, we know that the object should either travel in constant speed or at rest.
a-t graph of case 2
Case 3 : From this graph, the v-t graph and s-t graph are all increasing with concave downward shape.
a-t graph of case 3

The area enclosed by the graph between a certain time interval represents the change in velocity during that time interval.
how to interpret a-t graph
Oh, the graph with this shape again!!!. This time, it is a a-t graph. Let's see how to interpret it.
  • ab : Increasing acceleration (Velocity increases and the rate is faster and faster)
  • bc : Decreasing acceleration (Velocity still increases but the rate is slower and slower)
  • cd : Increasing deceleration (Velocity decreases and the decreasing rate is faster and faster)
  • de : Decreasing deceleration (Velocity decreases but the decreasing rate is slower and slower)

Can I be A Doctor One Day?

This morning I woke up quite early. As saying goes the early bird catches the worm, so if I were a bird of course now I’m flying over here and there looking for worms. But as  humankind I’m ‘flying’ through internet searching several things to write on. Huhu I don’t know what kind of thing should I ‘voice out’ in my personal blog. After all I remember that I got something that  to do; it should be beneficial if I continue writing on about “How to Become A Good and Successful medical student.  In accordance to  the title stated above it is something that I’m truly don’t know whether I’m in a right track or not. So let’s see what Prof said about it.
If you are determined and remain focused in your goal, have a strong discipline in your study methods and maintain a healthy attitude in your study and course work, you will succeed to become a doctor. You must be positive in your attitude during the process of becoming a doctor.
Recall the time in school when you were doing so well and were the teacher’s pet. (How can I recall if in my previous school I had never been my teachers’ as I always play truancy ). Recall how confident you were to speak in public and answer question intelligently in class. In every person there is tremendous potential and Allah permitting nothing or no one can come in your way from achieving your primary ambition.
Studying medicine requires that you remain organized, consistent, disciplined and interested throughout the five years of study. Each year in medical school may require different components of your capability in varying proportions such as the capability for understanding, synthesizing, evaluating, public speaking and communicating.
The list is too long to describe but you can rest assure that the training in medicine will make you become a wholesome person possessing good values and social skills.

1. Have I chosen the correct field?

According to this book the author assumed that the fact you are reading this book is an indication that you are aiming to become an excellent doctor. If you are person who is concerned about the well being of others and is always happy to lend a helping hand, then you are in the correct profession. Hmm it's that true of what did she wrote?? This is because i'm still wondering why i chose medical field as my choice. It's ok maybe there is 'something' that I couldn't find in myself why i chose it..because of money?interested in?fardhu kifayah? Of course the last one is true as it is good n useful for well being n it is indeed a profitable deeds.

Continue.. Prof in addition said that if u are ready to work hard n strive to know as much as possible about the human body so as to be able to relieve another human suffering, then you are off to a good start and will receive all the blessings of Allah. According to Prophet Muhammad (PBUH) there are five things that are very much encouraged to be performed.One of them is relieving the suffering of others. There is no job in trying to achieve this than being in the medical field, as people who come to you are those with some form of suffering, as it physical or mental.

Imagine the change you can make to the lives of others. As an example, imagine a person who is blind in both eyes due to bilateral cataract being able to see the very next day after surgery.

According to Prof's experience, she have seen many patients who are in tears after being able to see their loved ones once the eye bandage is removed following a cataract surgery. For many of them who appears morose before the operation, their facial expressions entirely change and their level of activity at home improves.

As a doctor you have the ability and opportunity to make a difference in people's lives.

Another hadith states that whenever a person leaves his house with the intention of helping another human being, Allah will give him the blessing equivalent to someone who performs "iktikaf" (meditates in the mosque) for a month.

So, a doctor who leaves his house to help other people will get the blessing from Allah all day long, provided he is sincere and does not expect any direst reward drom the person that he helps.

I (Prof) am sure by now you have realised that having a strong spiritual conscience would increase a person to become a doctor and help the needy.

How to become a good & successful medical student.

Yesterday my father bought me a motivational book on title "How to become a good & successful medical student". I thought that this book is really supportive n helpful for medical students n not only for them , I think it is good also for other students to follow though. As what at the front book displayed n written 'a holistic approach', it is of course useful for students due to its accomplished collection of discussion n custom problems raised faced by medical students is enthusiastically answered by the book author Prof. Dr. Muhaya Haji Mohamad M.D.,Ph.D of UKM. I have gone through the book and i think it is good if i could share with readers concerning the method n steps suggested by her. I hope that I won't do copyright infringement as i'll state along the resources n of course it is not done for money interest..
