Benefits and Costs of Physical Models

Some examples of physical models include bridges, cell models, human organs, crash test dummies, landform models, models of buildings, and models of chemical compounds.

Scale models are often used in architecture to build model bridges and buildings before the actual construction of the structure.

Building scale models as a hobby allows people to build to-scale model cars, boats, and trains.

<p>A physical model can be seen and touched, while a computer model can only be seen and manipulated onscreen, but not touched.</p> Signup and view all the answers

<p>A scale model is a smaller or larger version of an object that maintains the same proportions as the real object. They are useful for studying objects that are too large or too small to study directly.</p> Signup and view all the answers

<p>Physical models may not be able to be made large enough for their purpose, can be expensive to build and destroy, and cannot be used to study everything. They are also more expensive than computer models.</p> Signup and view all the answers

<p>A scale model is a model that is either smaller or larger than the actual object it represents. The proportions of the model should be the same as the real thing.</p> Signup and view all the answers

<p>Physical models allow for real-life testing that would be impossible outside of a model, they can be more accurate than computers for chaotic things like fluid flow, they are safer for certain kinds of experiments, and they are great for visualization and education.</p> Signup and view all the answers
