What is Physics?

Is it complicated or simple to understand?

What is the meaning of “Real time physics”?

How day-to-day life is co-ordinated with physics?

Let’s try to answer and solve. Correct me whenever I am wrong.

Physics is really very simple to understand if we don’t complicate ourselves with technical terms.

Actually, in our day-to-day life, knowingly or unknowingly, we use Physics.

Have you noticed the similarity between rotation and revolution of electrons around nucleus and the rotation and revolution of planets around the sun.

Actually it’s a great art by the Great God.

Have you felt a jerk in our body when stationary bus starts or when moving bus hits a speed breaker. That’s because of inertia (technical term).

So what’s inertia?

It’s very easy to understand when we try logically.

A normal human being likes to live a very normal life they can’t accept any sudden change in their life or its human tendency to resist the changes.

That’s what happens when our state (stationary state), is disturbed by the start or speed breaker, our body suddenly resists with jerk. Jerk didn't come as it is. It’s given externally by the start or speed breaker.

The inability of the body to change its state of rest or motion by itself is known as inertia.

Another confusing terms are Scalar and Vector.

Once grammar comes, English becomes complicated.

Similarly this vector quantity comes, understanding becomes complicated.

We may think what’s wrong with scalar, why should we go to vector?

What’s wrong with distance traveled (Scalar), why should we go to displacement (vector)?

It’s very simple to understand the importance of displace with the following example

Now just tell from A to A (ABCDEFA), what is the distance traveled by the person?

Very simple question, right. 5 + 3+ 2+ 2+ 3+1 = 16 kms

But what is the displacement of that person?

5+3-2-2-3-1 = 0 kms.

    Like some autowalas and taxiwalas, start and end at same place and get money for that. I think now we can understand the importance of displacement {vector quantity).

Though everyone knows it logically, when we say the technical term, vector quantity, it appears to be complicated.
