This animation can be used to illustrate such concepts as translation, velocity, acceleration, and uniform and non uniform motion along a straight line.

Click and drag the mouse on the screen to create a vector which you can move to illustrate the translational motion.

**Click** and **drag** on the screen to create a vector then **drag** it around the plane.

- To illustrate the notions of translation, velocity, acceleration and rectilinear motion.
- To perform average velocity calculations.

The **trajectory** of a point is the curve (even a straight line is deemed a curve) that dscribes its motion.

An object is in **translation** if all object points follow a parallel path. The…
