The stationary location from which we make our observations. This is the location within a reference frame from which an observer measures all positions and motions.

• Point of Reference

• Velocity Vector

• Frame of Motion

• Displacement Point

An imaginary line that contains an origin and is marked off in distance units.

• Coordinate Axis

• Number Line

• Vector Field

• Graph Paper

The ability to do work through the action of the electromagnetic field force on an object or by the electrical charges.
