physics.fisikastudycenter.com - 12 short-cut formulas for physics problems in mechanics with frictionless pulleys cases. These methods commonly used in multiple choices test or examination types not in an essay test type. Take a note that we have to be in exactly the same case with the each provided formula conditions to avoid any mistakes, if we don't, just leave it.

Formula 1
Frictionless floor, frictionless pulley (the masses of string and pulley are ignored), finding the acceleration of m₁ and m₂

Formula 2
Frictionless pulley, m₁ > m₂ , m₁ moves down, m₂ moves up, the acceleration:




Formula 3
A block in frictionless incline surface, without pulley
