Application of the Laws of Motion in Our Daily Life
The laws of motion may sound very geeky to most people and discussions over these laws as formulated by Sir Isaac Newton is better left in the classroom. These three laws of motion are fundamental in the discussion of mechanics in physics. However these laws are also basic in our lives even if we are too busy to notice it.
Now first let us refresh our memories on what these laws of motions are. Newton’s first law of motion states that a body continues to maintain its state of rest or of uniform motion unless acted upon by an external unbalanced force. This first law of motion is also called the law of inertia. From the latin word “iners” which means idle, this first law affirms that an object at rest will remain at rest unless otherwise an external force will cause it to move. An object in motion will remain in uniform motion following a straight line unless it is acted on by an external motion which causes it to change in direction or to decrease its speed.
This first law of motion can be exemplified by the use of a car. A car traveling on a highway at a fixed rate tends to maintain its motion and everything else inside the car are also moving at the same velocity as the car. When there is an outside force applied to the car in motion, like a sudden change in direction, although the car itself will respond to this sudden change, the passengers in the car or objects inside it are still responding to inertia, as such their motion will still be in a straight line when in fact the direction has already shifted causing the passengers or the objects to be thrown off.
Aside from the application of this law of motion in the physical sense, it can also be applied to how we live our lives. For example, we live each day doing the same things like waking up, going to work, returning home from work. These things becomes routine to us that unless we apply an external force, that is by doing something different to our lives we will remain in constant state of inertia.
The second law of motion states that the net force of an object is equal to the mass of the object multiplied by its acceleration or simply the law of acceleration. In physics, this law is used to determine the amount of force needed to make an object move or to make it stop. In life, this can also be stated as the success we achieve depends on the effort that we exert multiplied by inner values.
The third law of motion on the other hand is stated that to every action there is an equal and opposite reaction or the law of action and reaction. The illustration of this law in science is an object, let’s say a glass is on a table, even though the glass is at rest it is actually exerting force on the table and the table on the other hand is exerting equal opposite force thus making the glass unmoving. If there is imbalance to the exerted force then the glass would be thrown off the table. In life however, this may be best exemplified by the quote give and you shall receive. Show kindness and kindness will also be shown to you.
These three laws of motion may sound so scientific but its application in our daily life is so basic maybe we should make use of these laws to improve our life.
