Using Newton's second law to conduct a free-body analysis of a single object may have seemed difficult enough. Analyzing the inter-dependent motion of two objects may seem impossible. The Physics Classroom takes the mystery out of the topic with a logical presentation of a process for analyzing ... A free body diagram is defined as an illustration that depicts all the forces acting on a body, along with vectors that are applied by it on the immediate environs. Apart from the acting forces and subsequent work done, the moment magnitudes are also considered to be a part of such diagrammatic representations.

The free body diagram helps you understand and solve static and dynamic problem involving forces. It is a diagram including all forces acting on a given object without the other object in the system. You need to first understand all the forces acting on the object and then represent these force ...

(d) and (e), a Is there any difference between the free body diagram of fixed pulley and movable pulley? Not particularly. The main thing is that you can assume the fixed pulley isn't accelerating, so all forces on it must sum to zero. A movable pulley may or may not be accelerating. is it true that fixed pulley has T1 and T2, but movable has T2 on both sides ...
