The concepts of physics are applicable in our day to day life. One such concept is Kinetics and Kinematics that deals with motion. This concept is highly lucrative to prepare for the exams. In school or college days, if you are preparing for any competitive exams, the kinetics topic will surely help you sail through with an edge.
To help such students Vedantu has come up with an article prepared by a team of efficient teachers on kinetics. Kinetics and Kinematics - Introduction, Examples and Difference in Tabular Form could also be found in the PDF format from the website. The students can download it on their devices and study from the comfort of their homes. The resource is free of cost and doesn’t require any prior registration fee or signups.
In our day-to-day life, we observe the motion of various objects passing in front of us. Like a moving car, running animals, a ball descending downwards, people ascending to the mountains, flowing rivers. They are in motion and would continue to move, and come at rest whenever they want to.
Physics is all time with us to deal with all such motions, and the study of the motion of these objects in simple terms is called the Mechanics.
On this page, we will learn about the following:
Kinetics and Kinematics
What is the difference between Kinetics and Kinematics?
Difference between Kinetics and Kinematics in tabular form
Difference between Kinetics and Kinematics with example
An arm of science that deals with the efforts (why) of forces upon the motions of material bodies or with changes in a physical or chemical system.
Real-Life Examples of Kinetics
You studied how the enzyme affects the rate of biochemical reactions, torque, friction.
When a person pushes the ground backwards, the rough surface of the road reacts and exerts a forward force due to friction which causes the motion without friction, the person would have slipped and wouldn’t be able to move.
Here, in the above example, kinetics is dealing with the why of motion by considering the static frictional force.
A little boy switches on the button of the toy, and the toy starts rotating around the bar. Such a type of force that causes the body to rotate about the fixed axis is torque.
When the jar containing the gas is put on fire, the elastic collisions start between the molecules, this is due to the production of kinetic energy during the collision, called the Brownian motion. We can say that kinetics is also used in studying thermodynamics.
Throw a ball, what do you see? Surely a motion, isn’t it? Kinematics is connected to the motion of any object that exists in the world, starting from the smallest particles to the largest particles in the universe and even the fastest ones, photons.
Had there been no kinematics, no one would know the motion of the earth around the Sun, neither would there be the use of Cannonballs in wars. There would be no such games such as football or cricket if you talk about the real-life experience of kinematics.
The word Kinema means motion.
Suppose you have a wooden block of some weight suppose of 8 kg and you want to see that if this block would move, what would be its position, what time and speed would it take to travel a certain distance, and the path via which it would travel either it is Parabolic, Circular or straight, but not considering why it travelled this or that path or who made that block move?
In simple terms, Kinematics describes ‘how the motion is happening and doesn’t take into account why the body is moving, and who is setting that body into the motion?
Parameters in Kinematics
These four variables aid you in describing the motion accurately.
Let’s discuss a few examples by different types of motions:
Vertical Motion: Suppose you throw a stone, and you want to estimate its velocity whether there is any change in velocity or how much change is there, and the time it would take to hit the ground?
We haven’t described why that stone is descending, but only the attributes of the motion of that stone.
Horizontal Motion: Suppose you see a moving object let’s say, a car, you would contemplate the attributes such as:
How much it travelled in meters per second?
Does the velocity change?
How much is the change in the velocity?
Firing a cannonball
Shooting a basketball
An object such as a cannonball being fired or shooting a basketball at some angle from the horizontal. It will travel some distance up into the air before descending and hitting the ground, we can use a parabola to represent the locus of these objects.
The Fundamental Differences Between Kinetics and Kinematics
Having an Edge in Exams
Everyone prepares for the final exams but one must try to prepare in a manner one can keep oneself ahead of the others. Students must anchor their preparation to the direction that gives them an edge and score better. Before sitting for the final exam, one must have solved the previous year question papers. The previous year question paper tells a student what the examiner could ask and the manner one should answer the questions. Do sufficient revisions and take note of all the keywords in the notes. One can use Kinetics and Kinematics PDF available on Vedantu’s website for learning as well as revisions purposes.
Being prepared for the exams takes more than just being able to write perfect answers. One has to take care of personal health and lifestyle that adds to the performance of the day of the exam. Make sure one takes a good rest before the final exam, wake up fresh in the morning and walk in the exam hall with confidence.
One should go for the exam after having a good breakfast. An empty stomach is not for your mind, and can potentially make you tired easily before time. Take a water bottle in the examination hall, since keeping the body hydrated will take you far ahead in terms of managing yourself mentally, and unleashing potential in every way to attempt the questions paper with perfection.
Prepare yourself a day before the examination. Double-check all the stationery items that one will carry for the exam. Take a printout of the to admit card and put it in the folder. Make a checklist of all the necessary items that one will carry in the exam so one doesn't forget to take things in the exam.
Follow the above-mentioned tips offered by the expert teachers of Vedantu and turn yourself into a better plan maker.
