of a mental act performed entirely within the mind
The connection between the prefix "sub-" (under)and "-ject," (throw) is indirect, a little hard to see. To look at something subjectively is to be under the influence of personal opinion, experience, self-serving motivation, or emotion that underlies judgment.
the goal intended to be attained
The word "objective" (literally: "that at which we are thrown") is used as a noun in the example sentence. As a noun, "objective" simply means "goal" and is used interchangeable with the words "goal," "target," or "aim." As an adjective, to be "objective" is to be able to look at something without any personal or emotional attachment, with just the facts thrown at you.
put out or expel from a place
With the prefix "e-" meaning "out," and the root "ject-" meaning "to throw," it's clear to see that the word "eject" means "to throw out." However, when we remove the garbage from the house, we never say that we are "ejecting" it. The word "eject" is usually applied to either a forceful toss-out, or the removal of a member of the group, as in the example sentence.
force or drive (a fluid or gas) into by piercing
With the prefix "in-" meaning "into," and the root "ject-" meaning "to throw," it's clear to see that the word "inject" means "to throw into," although this word is usually used in a medical sense, in its noun form, "injection," known colloquially as "a shot." Shots, are, after all, thrown in some way, hence the connection.

With the prefix "con-" meaning "with," and the root "ject-" meaning "to throw," with a little imagination, we can see how the word "conjecture" derives its meaning of "an informed guess." A conjecture lies somewhere between a hypothesis (an educated guess) and a wild guess: a conjecture is a guess based on some facts thrown together with a hunch or two.

With the prefix "pro-" meaning "forward" and the root "ject-" meaning "to throw," and the suffix "-ile" transforming a noun into a verb, it's clear to see how that word "projectile" means an object that is thrown, usually against a target. Bullets, cannon balls, and paper airplanes are examples of projectiles.
the path followed by an object moving through space
With the prefix "tra-" being a form of the prefix "trans-" meaning "across," and the root "-ject" meaning "to throw," and the suffix "-ory" designating a noun, we can see how the word "trajectory" refers to a path of objects through space. But the word "trajectory" actually denotes more than that: A trajectory is a kind of pre-determined or predictable path, not only of physical objects, but of events in life as well. Key decisions that we make in life are said to set our trajectories.
the word class that qualifies nouns
With the prefix "ad-" meaning "toward," and the root "ject-" meaning "to throw," we can see how the word "adjective" has come to mean a word that is "thrown at," so to speak, a noun.
affected or marked by low spirits
With the prefix "de-" meaning, in this case, "down," and the root "ject-" meaning "to throw," we can see how the word "dejected" means "feeling low." To feel "dejected" is a little different from feeling "depressed." Usually, the word "dejected" is used when one's low spirits may be ascribed to a particular hurtful or disappointing event, while "depressed" usually refers to a more generalized and chronic sorrow.
most unfortunate or miserable
With the prefix "ab-" meaning "away" and the root "ject-" meaning "to throw," we can see how the word "abject" means, truly, "thrown away." Usually used as an adjective to modify "poverty" ("abject poverty") the word "abject" connotes a hopeless state and is a sad word to even contemplate, especially when applied to large groups of people, which it usually is.
to insert between other elements
With the prefix meaning "inter-" meaning "between," and the root "ject-" meaning "to throw," we can see how the word "interject" means "to interrupt."
