no answer text provided.

Explanation:

Question 1: By definition, force is a push or pull that can cause motion.
Question 2: A stronger force generally causes a greater acceleration, making the object (jar - lid) move faster and reach the end first.
Question 3: According to Newton's second law ($F = ma$), a stronger force on the same object results in a greater acceleration, which means a greater change in velocity.

Answer:

Question 1: D. force
Question 2: C. the STRONGER force
Question 3: A. a greater
