# 01. Model Specifics

For our second pass through the study of mechanics, we will eliminate one of the major restrictions in our original model. We will now allow objects to move through three-dimensional space. We will still, however, restrict our model with the following approximations.

**The object is acted on by constant forces.**

**The object’s size and shape are unimportant.**

**The object is classical.**
