“What Makes Things Move, Float, Stick, or Fall?”
You can’t see it. You can’t hold it. But force is everywhere — making things move, stop, float, fall, and stick!
Let’s meet 5 super forces that secretly work around you every day: 👉 Friction, Gravity, Buoyancy, Magnetism, and Air Pressure!
🎬 Real-Life Force Moments
1️⃣ Friction – The Sneaky Stopper
Minjun kicks a soccer ball. It rolls… and then stops.
That’s friction — the ground pushing back!
- Your shoes grip the ground
- You stop your bike with brakes
- Your pencil writes on paper
2️⃣ Gravity – The Great Puller
Soyul throws a ball into the air. It flies up… and falls down.
That’s gravity pulling everything toward Earth.
3️⃣ Buoyancy – The Floating Friend
Junho drops a rubber duck into the tub. It floats!
That’s buoyancy — water pushing up from below.
4️⃣ Magnetism – The Magic Grabber
Yuna sticks a magnet to the fridge. It clicks tight.
Magnetism pulls metal with invisible strength!
5️⃣ Air Pressure – The Invisible Squeezer
Sara squishes a plastic bottle. It crinkles fast.
That’s air pressure — invisible air pushing!
📊 Force Summary Chart
| Force | Direction | What It Does | Example |
|---|---|---|---|
| Friction | Pushes against | Slows or stops motion | Brakes, shoes |
| Gravity | Pulls downward | Makes things fall | Jumping, rain |
| Buoyancy | Pushes upward | Helps float | Boats, floats |
| Magnetism | Pulls metal | Attracts magnetic objects | Magnets, coins |
| Air Pressure | Pushes all around | Squeezes and supports | Straws, bottles |
