Hukum Kepler I, II dan III

1. Hukum I Kepler
Pada hukum persamaannya, Kepler menjelaskan tentang bentuk lingkaran orbit planet. Bunyi hukum ini sebagai berikut.

“Lintasan setiap planet mengelilingi matahari merupakan sebuah elips dengan matahari terletak pada salah satu titik fokusnya.

Gambaran orbit planet sesuai hukum I Kepler dapat dilihat seperti pada Gambar berikut ini

2. Hukum II Kepler
Hukum kedua Kepler menjelaskan tentang kecepatan orbit planet. Bagaimana kecepatan orbit planet tersebut? Perhatikan penjelasan berikut.

“Setiap planet bergerak sedemikian sehingga suatu garis khayal yang ditarik dari matahari ke planet tersebut mencakup daerah dengan luas yang sama dalam waktu yang sama.”

Coba kalian perhatikan Gambar berikut ini

Gambaran orbit planet sesuai hukum II Kepler

Garis AM akan menyapau lurus hingga garis BM, luasnya sama dengan daerah yang disapu garis Cm hingga DM. Jika tAB = tCD. Hukum kedua ini juga menjelaskan bahwa dititik A dan B planet harus lebih cepat dibanding saat dititik C dan D.
3. Hukum III Kepler
Pada hukum ketiganya Kepler menjelaskan tentang periode revolusi planet. Periode revolusi planet ini dikaitkan dengan jari-jari orbit rata-ratanya. Perhatikan penjelasan berikut.

“Kuadrat periode planet mengitari matahari sebanding dengan pangkat tiga rata-rata planet dari matahari.”

Hubungan di atas dapat dirumuskan secara matematis seperti persamaan berikut.
$T^{2}\sim R^{3}\mathbf{}$
$\mathbf{\left ( \frac{T_{1}}{T_{2}} \right )^{2}=\left ( \frac{R_{1}}{R_{2}} \right )^{3}}$
Contoh Soal :
Planet jupiter memiliki jarak orbit ke matahari yang diperkirakan sama dengan empat kali jarak orbit bumi ke matahari. Periode revolusi bumi mengelilingi matahari 1 tahun. Berapakah periode jupiter tersebut mengelilingi matahari?
Jawaban :
Diketahui
$R_{B}= R$
$R_{J}= 4R$
$T_{J}= 1 tahun$
Ditanyakan
$T_{B}= ........?$

"What I Like About You" 5 seconds of summer

Hey! Hey!

[Luke:]
That's what I like about you
You hold me tight
Tell me I'm the only one
Wanna come over tonight?
Yeah

[Michael:]
Keep on whispering in my ear
Tell me all the things that I wanna hear
'Cause it's true, that's what I like about you

[Calum:]
What I like about you
You really know how to dance
When you go up, down, jump around
Think about true romance, yeah

[Michael:]
Keep on whispering in my ear
Tell me all the things that I wanna hear
'Cause it's true, that's what I like about you

[Luke:]
That's what I like about you

(What I like about you)

That's what I like about you

(What I like about you)

That's what I like about you

(What I like about you)

That's what I like about you

Hey!

[Ashton:]
What I like about you
You keep me warm at night

[Ashton & Calum:]
Never wanna let you go
Know you make me feel alright

[Michael:]
Keep on whispering in my ear
Tell me all the things that I wanna hear
'Cause it's true, that's what I like about you

[Luke:]
That's what I like about you

(What I like about you)

That's what I like about you

(What I like about you)

That's what I like about you

(What I like about you)

That's what I like about you, you

That's what I like about you

"The Only Reason" 5 seconds of summer

[Michael:]
Don't talk, let me think it over
How we gonna fix this?
How we gonna undo all the pain?
Tell me, is it even worth it?
Looking for a straight line
Taking back the time we can't replace

[Luke:]
All the crossed wires,
Just making us tired
Is it too late to bring us back to life?

[Chorus:]
When I close my eyes and try to sleep
I fall apart, I find it hard to breathe
You're the reason, the only reason
Even though my dizzy head is numb,
I swear my heart is never giving up
You're the reason, the only reason

[Calum:]
I feel you burning under my skin
I swear I see you shining
Brighter than the flame inside your eyes

[Ashton:]
Bitter words spoken,
Everything broken
It's never too late to bring us back to life

[Chorus]

Oh, oh, oh, only reason, the only reason
Oh, oh, oh, only reason, the only reason

[Michael:]
Don't talk, let me think it over
How we gonna fix this?
How we gonna undo all the pain?

[Chorus x2]

"Heartache On The Big Screen" 5 second of summer

[Luke:]
Started out like in the movies
But it ended like a bad dream
Curtain opened, heard the crowd roar
This one's a repeat, seen it before

[Calum:]
Rewind to the start before it all went wrong
What's going on?

[Luke:]
Fast forward to the end, after everyone's gone home
And they've forgotten it all

[All:]
This ain't a movie that I wanna see
A tragic story, starring you and me
Yell "cut", we're stuck inside this scene
This is heartache on the big screen
The clock is ticking, and I'm out of time
The camera's rolling, and I forgot my lines
My script is ripped and now I see

[Luke:]
This is heartache on the big screen
This is heartache on the big screen

[Calum:]
Curtain closes on this cliché
A good story of a bad day
Back to square one, where I started
As I stand here, broken-hearted

Fast forward to the end, after everyone's gone home
And they have forgotten it all

[All:]
This ain't a movie that I wanna see
A tragic story, starring you and me
Yell "cut", we're stuck inside this scene
This is heartache on the big screen
The clock is ticking, and I'm out of time
The camera's rolling, and I forgot my lines
My script is ripped and now I see

[Luke:]
This is heartache on the big screen

[Michael:]
If Hollywood could see me now
I'd get the starring role
But they won't so I'll just keep on acting a fool

[Luke:]
This ain't a movie that I wanna see
A tragic story, starring you and me
Yell "cut", we're stuck inside this scene
Yeah

[All:]
The clock is ticking, and I'm out of time
The camera's rolling, and I forgot my lines
My script is ripped and now I see

[Luke:]
This is heartache on the big screen
This is heartache on the big screen
This is heartache on the big screen

"Jasey Rae" 5 seconds of summer

[Luke:]
Lights out,
I still hear the rain,
these images that fill my head.

[Luke Calum:]
Now keep my fingers from making mistakes,
tell my voice what it takes,
to speak up,
speak up,
and keep my conscience clean when I wake.

[All:]
Don't make this easy,
I want you to mean it, Jasey.
(Say you'll mean it.)
You're dressed to kill,
I'm calling you out.
(Don't waste your time on me.)

[Calum:]
Now there's an aching in my back,
a stabbing pain that says I lack,
the common sense and confidence,
to bring an end to promises,
that I make in times of desperate conversation,
hoping my night could be better than this in the end.
Just say when.

[All:]
Don't make this easy,
I want you to mean it, Jasey.
(Say you'll mean it.)
You're dressed to kill.
I'm calling you out,
(Don't waste your time on me.)

I've never told a lie
and that makes me a liar.
I've never made a bet,
but we gamble in desire.
I've never lit a match,
with intent to start a fire.
But recently the flames,
are getting out of control.

Call me a name,
kill me with words,
forget about me,
it's what I deserve.
I was your chance,
to get out of this town,
but I ditched the car
and left you to,

Wait outside,
I hope the air will serve to remind you,
that my heart is as cold as the clouds of your breath
and my words are as timed as the beating in my chest.
