🌍 Gravitation – CET Physics Formula Sheet


🔹 Universal Law of Gravitation:

    F = (G × m₁ × m₂) / r²


🔹 Gravitational Field (g):

    g = GM / r²


🔹 Gravitational Potential Energy (U):

    U = –GMm / r


🔹 Escape Velocity (vₑ):

    vₑ = √(2GM / R) = √(2gR)


🔹 Orbital Velocity (vₒ):

    vₒ = √(GM / r)


🔹 Kepler’s Laws (Short Notes):

    1. Orbit = Elliptical

    2. Equal areas in equal time

    3. T² ∝ r³


📌 Tip:

– Use G = 6.67×10⁻¹¹ Nm²/kg²  

– g = 9.8 m/s²  

– Practice numericals with sign conventions!

CET Physics: Electricity – Important Formulas & Short Notes by sarthak patil

 🔋 Key Concepts: Electric Current (I): Flow of electric charge. 👉 Unit: Ampere (A) Voltage (V): Electric potential difference. 👉 Unit: Volt (V) Resistance (R): Opposition to the flow of current. 👉 Unit: Ohm (Ω) --- 🔌 Important Formulas: 1. Ohm’s Law: 🔸 V = I × R 2. Power (P): 🔸 P = V × I 🔸 P = I² × R 🔸 P = V² ÷ R 3. Electrical Energy: 🔸 E = P × t (in Joules) 🔸 E = P × t ÷ 1000 (in kWh) --- 🧮 Resistor Combinations: Series: 🔸 R_total = R₁ + R₂ + R₃ + ... Parallel: 🔸 1/R_total = 1/R₁ + 1/R₂ + ... --- 🧠 Tips to Remember: Series Circuit: 🔹 Current = Same 🔹 Voltage = Divided Parallel Circuit: 🔹 Voltage = Same 🔹 Current = Divided Power increases with square of current! --- 📌 Posted by: Sarthak Prakash Patil 📖 Sarthak’s Education Corner
