Some Physical Laws

 

F = ma       (Newton’s 2^nd Law)

F_c = mv² /r      (Centrifugal-Centripetal Force
                       Due to a Curved Path)

F_g = G m₁m₂ /d²        (Universal Law of Gravity)

K.E. = ¹/₂ mv²        (Law of Kinetic Energy)

         

m=mass, v=velocity, a=acceleration, F=force, r=radius, d=distance, G=gravitational constant, KE=kinetic energy
