This tag is for the classical concept of forces, i.e. the quantities causing an acceleration of a body. It expands to the strong/electroweak force only insofar as they act comparable to ‘classical’ forces. Use the [particle-physics] tag for decay channels due to forces and [newtonian-mechanics] or one of the other subtopics of [classical-mechanics] for the dynamics of classical systems.

Why can't I choose blocks attached with pulley B as a system?
Three blocks of masses m1, m2 and m3 are connected as shown in the figure. All the surfaces are frictionless and the string and pulleys are light. Find the acceleration of the block of mass m1.

Why acceleration does not vary, when an equal force is applied in a pulley system? [closed]
In the figure $m_{1} = 5$ Kg and $m_{2} = 2$ Kg and $F = 1$ N. Find the acceleration of either block. (The mass of the string and pulley is negligible and the pulley is frictionless)
I solved …
