Lift Upward Motion & Apparent Weight — NTSE in 59 Sec ⚡
❓ Question Why does a person feel heavier when a lift accelerates upward? 🖼️ Concept Image ✍️ Short Solution This is a pure Newton’s Second Law + apparent weight concept. No calculation needed — just force direction clarity + equation setup 🔥 🔹 Step 1 — Actual vs Apparent Weight (MOST IMPORTANT 💯) Actual weight: Actual Weight = m g \text{Actual Weight} = mg 👉 Yeh constant hota hai (Earth ki gravity par depend karta hai) Apparent weight: Apparent Weight = N \text{Apparent Weight} = N 👉 Jo tum feel karte ho = Normal Reaction 🔹 Step 2 — Normal Reaction = What You Feel 👉 Lift ke floor ka jo force tum par lagta hai, wahi: N = Apparent Weight N = \text{Apparent Weight} 📌 Weighing machine bhi N measure karti hai, mg nahi 🔹 Step 3 — Lift Moving Upward 👉 Jab lift upar accelerate karti hai , system ko upward accelerate karne ke liye extra force chahiye hota hai. 👉 Isliye floor tumhe extra push deta hai. 🔹 Step 4 — Apply Newton’s Seco...
