Why are system schemas important?

Question

System schema are a useful representational tool for capturing important elements about the system we are trying to describe. It is easiest to understand the system schema by using an example to draw upon. The situation below will provide a context for drawing the system schema, and for representing a force diagram. 20 авг. 2012 г.

What is the purpose of a system schema?

A system schema consists of identifying and labeling all objects of interest from a given physical situation, as well as all the different types of interactions between the objects.

What does the dotted line in the system schema represent?

Before, during, and after the collision is represented here by a single system schema. Therefore, the contact interaction between cart A and cart B is drawn as a dotted line rather than a solid line to indicate that it is not present for the entire time interval of interest of the schema.

What is a force diagram in physics?

In physics and engineering, a free body diagram (FBD; also called a force diagram) is a graphical illustration used to visualize the applied forces, moments, and resulting reactions on a body in a given condition.
