speed
Step-by-step explanation:
because monent= force x perpendicular distance which would create a rotating effect.
Translation involves moving un a straight line and without rotating.
inertia can't be the answer because the law of inertia :
it states that the body will remain in rest until a external force is released.
Speed describes change in the distance with time which inly occurs during translation. Thanks, by God's grace you will surely pass
