Expert writing Tips
Best practice
When describing movement in technical contexts, use "trajectory of motion" to clearly indicate the calculated or observed path followed by an object or entity. This phrase is particularly useful in scientific and engineering writing for its precision.
Common error
Avoid using "trajectory of motion" when simply referring to a general direction or tendency. "Trajectory" implies a specific, calculated path. If the path is not precisely defined, consider using terms like "direction of movement" or "general course" instead.
