Question

read the diagram how does the acceleration arrows direction relate to the direction of the velocity arrows when an object speeds up and slows down?

Explanation:

When an object speeds up, the acceleration arrow is in the same direction as the velocity arrows. When an object slows down, the acceleration arrow is in the opposite direction of the velocity arrows. This is because acceleration is the rate of change of velocity. In the case of speeding - up, velocity is increasing in the same direction, and in the case of slowing - down, velocity is decreasing (opposite change).

Answer:

When an object speeds up, the acceleration arrow is in the same direction as the velocity arrows. When an object slows down, the acceleration arrow is in the opposite direction of the velocity arrows.
