Give an example of three-dimensional motion.

Explanation

### Step-by-Step Solution:

1. **Understanding Three-Dimensional Motion**:
- Three-dimensional (3D) motion refers to the movement of an object in three different directions or axes: the x-axis, y-axis, and z-axis. This means that the object can move forward and backward (x-axis), left and right (y-axis), and up and down (z-axis).

2. **Identifying Characteristics of 3D Motion**:
- For an object to be in 3D motion, it must change its position in all three axes over time. This can be represented mathematically with coordinates (x, y, z) that change with respect to time.
