🌍 Gravitation – CET Physics Formula Sheet


πŸ”Ή Universal Law of Gravitation:

    F = (G × m₁ × m₂) / r²


πŸ”Ή Gravitational Field (g):

    g = GM / r²


πŸ”Ή Gravitational Potential Energy (U):

    U = –GMm / r


πŸ”Ή Escape Velocity (vβ‚‘):

    vβ‚‘ = √(2GM / R) = √(2gR)


πŸ”Ή Orbital Velocity (vβ‚’):

    vβ‚’ = √(GM / r)


πŸ”Ή Kepler’s Laws (Short Notes):

    1. Orbit = Elliptical

    2. Equal areas in equal time

    3. T² ∝ r³


πŸ“Œ Tip:

– Use G = 6.67×10⁻¹¹ Nm²/kg²  

– g = 9.8 m/s²  

– Practice numericals with sign conventions!
