Sci-Labyrinth | Physics

Force and motion describe how all objects move or stay still around us. Every push or pull changes how things move — like how a ball rolls, falls, or stops. When objects interact, their motion follows clear rules or laws. These laws explain how speed, direction, and force work together. Over time, these ideas help us understand everything from walking to how cars and machines work.

In short, motion changes only when a force acts on it, and every action always has an equal and opposite reaction.

Why? because sound requires physical molecules to vibrate, it cannot travel through a vacuum. Space is a vacuum with no matter to carry sound waves, it is entirely silent. However, scientists can still "hear" the cosmos through data sonification—a process that translates raw space measurements (like radio emissions, x-rays, and plasma waves) into audible sounds. This is proven by Robert Boyle in 1660, in the experiment he used a vacuum pump to slowly remove air from sealed glass jar with a ringing bell inside, as the air was taken out of the jar, the sounds became silently.

Earth Day is not just about celebration, it's about ACTION. It is a reminder for our shared responsibility to proteect and care our Mother Earth. Here are simple yet impactful ways we can help!

💧 Conserve Water
♻️ Reduce Waste
🌱 Stay Aware and Take Action
🌳 Plant More Trees

Earth Day is celebrated every April 22. It began in 1970 in the United States, founded by Senator Ga***rd Nelson, as a way to raise awareness about environmental issues and inspire people to take action in protecting our planet.

Together, we can make a difference.
Let us all love our nature, now or never! ✨

Love, Lab-Coated 🧪💘

What we call “kilig” isn’t just a feeling, it’s also science! 💗

When you’re around someone you admire, your brain releases chemicals like dopamine, oxytocin, and adrenaline. These affect your thoughts, your emotions, and even your heartbeat!

✨️ Love may feel magical, but it’s also measurable ♡

This Valentine’s season, we’re putting emotions under the microscope, because even the heart has a little science behind it!

𝘏𝘢𝘱𝘱𝘺 𝘷𝘢𝘭𝘦𝘯𝘵𝘪𝘯𝘦'𝘴 𝘥𝘢𝘺, 𝘦𝘷𝘦𝘳𝘺𝘰𝘯𝘦! 🌷

🔍🧬𝐒𝐂𝐈-𝐋𝐀𝐁𝐘𝐑𝐈𝐍𝐓𝐇 𝐖𝐄𝐄𝐊𝐋𝐘 𝐐𝐔𝐄𝐒𝐓𝐈𝐎𝐍 : Evolutionary Biology

Natural selection is a process by which living organisms gradually change over generations due to differences in their traits.

Within a population, individuals are not exactly the same. They have variations in characteristics such as size, color, strength, or resistance to disease. Some of these traits help an organism survive better in its environment. Individuals with advantageous traits are more likely to survive, reproduce, and pass those traits on to the next generation.

Over time, these helpful traits become more common in the population, while less useful traits may disappear. This gradual change explains how species adapt to their environment and how new species can eventually arise.

In short, natural selection means that organisms best suited to their environment are more likely to survive and reproduce, leading to evolutionary change over long periods of time.

Question:
🧬 Who is known as the proponent of the theory of evolution by natural selection?
Options:
👍 Like – Charles Darwin
❤️ Heart – Galileo Galilei
😮 Wow – Isaac Newton
𝗟𝗮𝘀𝘁 𝗪𝗲𝗲𝗸'𝘀 𝗔𝗻𝘀𝘄𝗲𝗿 : ❤️ Proton ( 48/48 ! )
Stay tuned for the answer and for another question next week! 💚

🔍👨‍🔬𝐒𝐂𝐈-𝐋𝐀𝐁𝐘𝐑𝐈𝐍𝐓𝐇 𝐖𝐄𝐄𝐊𝐋𝐘 𝐐𝐔𝐄𝐒𝐓𝐈𝐎𝐍 : Chemistry

Atoms are known as the basic building blocks of everything in the universe, but they aren't just a solid balls. Instead, they are made up of three primary subatomic particles, each with its own specific location and electric charge. One of these particles is known for having a positive charge and resides deep within the atom's nucleus.

These charges is essential because the balance between positive and negative particles is what holds atoms together and allows them to form chemical bonds.

Question:
🧪 What scale is used to measure the strength or magnitude of an earthquake?
Options:
👍 Like – Neutron
❤️ Heart – Proton
😮 Wow – Electron
𝗟𝗮𝘀𝘁 𝗪𝗲𝗲𝗸'𝘀 𝗔𝗻𝘀𝘄𝗲𝗿 : 😮 Richter Scale ( 11/11 ! )
Stay tuned for the answer and for another question next week! 💚

💡𝘿𝙄𝘿 𝙔𝙊𝙐 𝙆𝙉𝙊𝙒?
That sudden tummy-drop feeling you get on drop towers and roller coasters is caused by free fall, inertia, and changes in apparent weight. When the ride suddenly drops, your body and the seat begin moving downward together because of gravity. For a brief moment, the seat pushes up on your body much less than usual, making you feel lighter or almost weightless.

Your internal organs, especially your stomach, don’t respond instantly to this sudden motion because of inertia—the tendency of objects to resist changes in motion. As a result, your stomach briefly lags behind your body, creating that sinking or fluttery sensation.

Your brain interprets this sudden change in forces as your stomach “dropping,” even though your stomach doesn’t actually move or fall. It’s simply your body adjusting to the rapid change in motion and gravity.
