Average Speed: total distance an object traveled by the total time it has traveled
Displacement: how far an object has moved from its original position; the difference between the final and initial positions
Motion: an object changes its position
Speed: the distance an object moves per unit of time, such as miles per hour
Velocity: speed in a direction

Decreasing: becoming smaller or fewer in size, amount, intensity, or degree
Displacement: the moving of something from its place or position.
Distance: the total movement of an object without any regard to direction
