Tugging a small toy with your dog can be a lot of fun—but it’s also a great way to experiment with forces acting on an object. Forces are what scientists call the pushing and pulling on objects. In ...

Determining whether or not a mechanism will work before building physical prototypes can be time consuming and challenging, especially for new designs. At one time, only physical prototypes made it ...

When computer-aided engineering (CAE) methods became available for design work in the 1980s, finite element analysis (FEA) was the first to be widely adopted. Over the years, it's helped design ...

Find out how forces and motion make our world move in the Science Trek: The Web Show. The world is full of motion and motion happens because of force. On this episode of Science Trek: The Web Show, ...

Why do things fall? It’s about force and motion. Find out more in this Science Trek short. A force is basically a push or a pull. Forces like gravity, inertia, and momentum affect everything. On this ...

The VI-Grade DiM500 system at Bridgestone's Rome facility enables virtual tire testing before physical prototypes are ...

Maynard Zettler, director of research and engineering, Naval Air Warfare Center Training Systems Division, discussed the Navy’s simulation activities (Box 2-1). The important focus was on the Naval ...

Scientists often make measurements. The physical quantities they measure fall into two categories: scalars and vectors. Scalar and vector quantities are treated differently in calculations. Motion - ...
