Gravitron can be weakened by explaining the difference between distance and displacement. what is the difference?

Both distance and displacement give you the length between two points, however, they are not the same:

Distance:
1- It is a scalar quantity, meaning that it has only a magnitude and no direction
2- It indicates the actual length of the path between the two points, or the length moved whether it is the shorthest length or not.
3- It is not a unique path, as each one can follow his own path to get from point to another.
4- It is calculated using the rule: speed*time

Displacement:
1- It is a vector quantity, meaning that it has both a magnitude and a direction.
2- It indicated the length of the shortest path between two points.
3- It is a unique path
4- It is calculated using the rule: velocity*time
