drag & drop the answer
force
weakness
greater
strength
lesser
arrow
move or accelerate
note: use ctrl+d to drag the option via keyboard

Explanation:

The problem is about describing a force. A force is described by its strength (magnitude, measured in newtons) and the direction (represented by an arrow) in which it acts. So we need to match "strength" with the first blank (related to newtons, as newtons measure the magnitude/strength of force) and "arrow" with the second blank (as arrows represent direction of force).

Answer:

First blank: strength; Second blank: arrow
