Displacement
### Formula:
$$\Delta x = x_f - x_i$$
### Terminologies:
- $$Δx$$ → Displacement; change in position of an object.
- $$x_f$$ → Final position; position of the object at the end of motion.
- $$x_i$$ → Initial position; position of the object at the beginning of motion.
### Usage:
- Used to find the shortest directed distance between initial and final positions.
