Is it difficult for your younger siblings to learn physics?

Now that is because the younger siblings learn the wrong way,

The siblings always ship out complicated physics formulas.

Indeed, it is difficult to memorize physics formulas and much more. Even though you memorize all the physics formulas, it doesn't mean you can work on physics problems, now that's what makes it difficult for you to learn physics, right?

Now I will tell you an easy way to learn physics, namely by common sense (logic).

Here's how: younger siblings remind the number of Pythagoras:

6  8  10

Logically :

Everything is enlarged except for the length, so that it can be formulated as follows:

L '= k L0 (decrease)

M '= k m0 (enlarge)

T '= k T0 (enlarge)

Ek = (k-1) E0 (enlarged)

Where k is a comparison of the unremarked Pythagorean numbers with the largest Pythagorean number.

So now we try to take modern physics questions from SMPTN questions:

1. Two twins David and Boby travel in space with a spacecraft speed of 0.8 C. After 12 years of traveling David returned to earth. So according to Boby David's journey has been going on for… years.

       A. 12     B. 15     C. 20     D. 10     E. 8

 Answer: C. 20

Logic Way:

speed 0.8 c, meaning 8/10, so the number that hasn't come out is 6 and the greatest number is 10.

 Remember pitagoras: 6 8 10, the numbers that have not been drawn are connected to the largest number, so that you get 6/10 or 10/6. Because time moves bigger then

T '= (10/6) X 12 = 20.

the real way:

delta t '= delta t / (root (1 - v ^ 2 / c ^ 2)) = 12 / (root 1 - (0.8c) ^ 2 / c ^ 2) = 12 / root (1-0.64) = 12 / root 0.36 = 12 / 0.6 = 20.
