Question

read the following selection from the section
ewton’s first law of motion.\ then, fill in the blank.

newton’s first law of motion states that an object in motion tends to stay in motion. it does so, unless an external force acts upon it to change its motion. similarly, if the object is at rest, it will remain at rest unless an unbalanced force acts on it.

the word \external\ in the sentence above tells the reader that _____.

a the force acting upon the object is stronger than the other force
b the force acting upon the object is weaker than the other force
c the force acting upon the object is acting from outside of it
d the force acting upon the object is coming from within it

Explanation:

To solve this, we analyze the meaning of "external". "External" means related to the outside. Option A and B talk about force strength, which isn't related to "external". Option D says the force is from within, which is the opposite of external. Option C says the force is from outside, which matches the meaning of "external".

Answer:

C. the force acting upon the object is acting from outside of it
