The beauty of the world is a result of physics by @officialsay04

Falling Faster Than Gravity – What’s Really Happening?
In this experiment, a ball is released near the top of an inclined ruler, while a cup is placed further down the slope. As the ball is released, it falls and lands directly into the moving cup.
At first, this seems surprising. Intuitively, one might expect the ball to fall straight down and miss the cup. However, physics explains why this does not happen.
When the ball is released, it starts from rest and accelerates downward due to gravity (g). At the same time, the cup is moving along the inclined plane.
The key idea is that both the ball and the cup share the same horizontal component of motion. Gravity only affects vertical motion, not horizontal motion.
Because of this, the horizontal positions of both the ball and the cup remain aligned as they move. While the ball is falling vertically, the cup moves horizontally in such a way that it stays directly beneath the ball.
As a result, the ball lands perfectly inside the cup. by @officialsay04

☢️ TYPES OF RADIATION
Radiation is energy emitted from radioactive materials. There are three main types:
🟡 1. Alpha radiation (α)
✔️ What is it?
A heavy particle made of:
2 protons
2 neutrons
👉 (basically a helium nucleus)
🧱 Penetration power:
Very low
Can be stopped by a sheet of paper
⚠️ Danger:
Cannot pass through skin
But dangerous if:
inhaled
or swallowed
🔵 2. Beta radiation (β)
✔️ What is it?
A small particle:
electron (β⁻)
or positron (β⁺)
🧱 Penetration power:
Medium
Can pass through paper
Stopped by aluminum
⚠️ Danger:
Can penetrate the skin
Can damage body cells
🟣 3. Gamma radiation (γ)
✔️ What is it?
A high-energy electromagnetic wave
Not a particle like alpha or beta
🧱 Penetration power:
Very high
Can pass through:
metal
concrete
⚠️ Danger:
Extremely dangerous
Can pass through the whole body
Can damage DNA by @officialsay04

3. 🌊 Splashdown (kutua baharini)
Hatimaye:
Orion inagusa maji ya bahari taratibu
Hutua kwenye Pacific Ocean (Bahari ya Pasifiki), karibu na pwani ya California, USA
4. 🚢 Uokoaji
Baada ya kutua:
Meli za uokoaji za NASA zinawasogelea
Wanaanga hutolewa ndani ya chombo
Wanapokewa kama mashujaa
🎯 HITIMISHO
Safari ya Artemis II inaonyesha kitu kikubwa:
👉 Binadamu wanaweza kusafiri mwezini
👉 Na bado kurudi salama duniani kupitia bahari 🌍🌊 by @officialsay04

🌊 JINSI WANAVYOTUA BAHARINI (SPLASHDOWN)
Baada ya kuzunguka Mwezi, Orion inarudi duniani kwa hatua hizi:
1. 🔥 Re-entry (kuingia anga ya dunia)
Chombo cha Orion spacecraft kinaingia kwenye anga ya dunia kwa kasi kubwa sana.
Joto linakuwa kali sana (kama nyota inayowaka)
Ngao maalum ya joto hulinda chombo
2. 🪂 Kupunguza kasi kwa parachutes
Chombo kinapokaribia dunia:
Parachutes kubwa 3 hutokea
Hupunguza kasi polepole sana
Kama “maua makubwa angani” yanayofunguka 🌼 by @officialsay04

👨‍🚀 CREW WA ARTEMIS II
Wanaanga 4 walioteuliwa kwa safari hii ni:
🇺🇸 NASA (USA)
Reid Wiseman – Commander (kiongozi wa safari)
Victor Glover – Pilot (anayeendesha chombo)
Christina Koch – Mission specialist
🇨🇦 CSA (Canada)
Jeremy Hansen – Mission specialist
🚀 CHOMBO WALICHOTUMIA
Safari imetumia:
Orion spacecraft → chombo cha kubeba wanaanga
Space Launch System → roketi ya kurusha chombo angani by @officialsay04
