### Dynamics Snapshot

This section is about forces - the cause of motion. After giving the definition of force, a number of forces acting in objects and systems of objects are provided and analyzed. Then, Newton's Laws of Motion as the keystone of dynamics are discussed. You will be able to learn concepts such as inertia, friction coefficient, and terminal velocity that determine the rate of motion change. Each concept is explained step-by-step and is illustrated by a number of examples for clear understanding.

### Dynamics Calculators

In addition to the Dynamics tutorials, we also provide online Dynamics Calculators which allow you to calculate specific Dynamics formula in support of the tutorials or to check and verify your own calculations in support of your homework, coursework or thesis.

The following Physics Calculators are provided in support of the Dynamics tutorials.
