## 12 shortcuts in physics mechanics - pulleys

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

Formula 4
Frictionless floor surface, frictionless pulley (ignoring the masses of string and pulley), m1 moves down, m2 moves to the left.

Formula 5
Frictionless floor surface, frictionless pulley (ignoring the masses of string and pulley), m1 moves down, m2 moves up.

Formula 6
Frictionless floor surface, frictionless pulley (ignoring the masses of string and pulley), m1 moves down, m2 moves up.

Formula 7
Frictionless floor surface, frictionless pulley (ignoring the masses of string and pulley), m1 moves down, m2 moves to the right.

Formula 8
Frictionless floor surface, frictionless pulley (ignoring the masses of string and pulley), m1 and m2 move to the right.

Formula 9
Frictionless floor surface, frictionless pulley (ignoring the masses of string and pulley), m1 moves down, m2 moves to the right.

Formula 10
