Velocity & Acceleration

For any given motion, the distance is ____.

• the direction which an object moves
• the scalar of the object's velocity
• how far out of place which the object finishes relative to the starting location.
• the amount of ground which is covered by the moving object.

For any given motion, displacement is ____.
