Explainer Zone on Instagram: "Newton’s First Law, also called the Law of Inertia, states that an object will remain at rest or continue to move in a straight line at constant speed unless acted upon by an external force. For example, when a car suddenly stops, the passengers inside tend to move forward. This happens because their bodies were in motion with the car and want to continue moving due to inertia, even though the car has stopped. Seat belts provide the external force needed to stop the

Physics Uncovered on Instagram: "When temperatures drop, atoms slow down — and that slowdown makes materials contract. This process is called thermal contraction, the opposite of thermal expansion. ❄️➡️📏 You can actually see it around you: power lines tighten in winter, and roads can crack when the ground gets cold and contracts. It’s a subtle but powerful reminder that even solid objects are in constant motion — just slower than you think. ⚙️ #science #physics #explore #reels #learnsomethingne
