Class 11 Physics Formula Sheet (Kerala/NCERT
Syllabus)
1. Units & Measurements
• Dimensions: [M^a L^b T^c]
• Mean = (x■ + x■ + … + x■)/n
• Absolute Error = |Measured − True|
• Relative Error = (∆x/x) × 100%
• 1 Å = 10■¹■ m, 1 u = 1.66×10■²■ kg
, 2. Motion in a Straight Line
• v = u + at
• s = ut + (1/2)at²
• v² = u² + 2as
• s = (u+v)t / 2
