Скачать или смотреть Physics Chapter 1 🔥 Units, Dimensions & Errors | ZeroVoice Academy

🔴 INTRO (0:00 – 0:10)

Screen: Aesthetic black background + glowing text
Text: “Units, Dimensions & Errors – Chapter 1”
Background: Soft ambient music

Narration (optional/no voice):
“Welcome to ZeroVoice Academy. Let’s quickly master Units, Dimensions & Errors.”


---

🟦 SECTION 1: What Are Units? (0:10 – 0:40)

Screen: Icons of meter, second, kilogram
Text:

Unit = standard for measurement

Two types: Fundamental & Derived

SI Units = globally accepted


Important points to show:

Fundamental units (m, kg, s, K, A, mol, cd)

Derived units (N, J, Pa, W, etc.)



---

🟧 SECTION 2: Physical Quantities (0:40 – 1:10)

Screen: Animated shapes showing length, mass, time
Text:

Physical Quantity = measurable quantity

Types: Scalar & Vector


Include examples:

Scalar: mass, time

Vector: force, velocity



---

🟩 SECTION 3: Dimensions (1:10 – 1:45)

Screen: Dimensional formula box
Text:

Dimensions = powers of fundamental units

[Force] = M¹L¹T⁻²


Show Top Dimensional Formulas:

Velocity → L T⁻¹

Acceleration → L T⁻²

Force → M L T⁻²

Energy → M L² T⁻²



---

🟨 SECTION 4: Dimensional Analysis (1:45 – 2:15)

Screen: Equation check animation
Text:

Used for: Checking correctness of equations

Finding units & relations


Example:

T = 2π√(L/g)



---

🟥 SECTION 5: Errors (2:15 – 3:00)

Screen: Warning triangle + measurement tools
Text:

Types of Errors:

Systematic (Zero error, Instrument error)

Random

Gross



Show formula:

Absolute error = |True value – Measured value|

Percentage error = (Error / True value) × 100

Mean error concept



---

🟪 SECTION 6: Significant Figures (3:00 – 3:40)

Screen: Table of sig fig rules
Text:

Non-zero digits → significant

Zeros between digits → significant

Trailing zeros (after decimal) → significant


Example:

1.230 → 4 sig figs

205 → 3 sig figs



---

🟫 SECTION 7: Numerical Examples (Optional) (3:40 – 4:30)

Screen: Simple animation + bold numbers
Give 2–3 exam-level questions:
1️⃣ Find the dimensions of pressure
2️⃣ Find % error when value = 10 ± 0.2
3️⃣ Check if v² = u² + 2as is dimensionally correct
