1. CHS Physics Motion in Two and Three Dimensions

2. Position  The position of an object in two or three dimensions is given by a position vector.  The vector is anchored at the origin of the coordinate system.

3. Displacement  This is still the change in position.  Written as a vector equation.

4. Velocity  The definitions remain the same  They are only written in vector notation.

5. Instantaneous Velocity  The direction is always tangent to the path.  It can be written in unit vector notation.

6. Acceleration  Same as before

7. Instantaneous Acceleration  This can also be written in unit vector notation
