Understanding the Verb for Newton's Discovery
The question asks us to select the most appropriate word to complete the sentence "Newton ______ the laws of gravitation." This requires choosing the correct verb tense to describe a historical event performed by Isaac Newton regarding the laws of gravitation.
Let's look at the options provided:
- Option 1: was discovered
- Option 2: had discovered
- Option 3: discovered
- Option 4: Discovering
We need to analyze which verb form correctly fits the sentence structure and context.
Analyzing the Options:
- Option 1: was discovered
This is in the passive voice ("Newton was discovered"). This implies that someone discovered Newton, which is not the meaning intended. The sentence needs a verb describing what Newton *did*. Therefore, this option is incorrect. - Option 2: had discovered
This is in the past perfect tense. The past perfect ("had discovered") is used to talk about an action that happened before another action in the past. For example, "By the time I arrived, Newton had discovered the laws of gravitation." In the simple sentence given, there is no other past action mentioned for "had discovered" to precede. It is not the most direct or appropriate tense for describing a single, completed historical action like Newton's discovery. - Option 3: discovered
This is in the simple past tense. The simple past tense ("discovered") is used to talk about an action that started and finished at a specific time in the past. Newton's work on the laws of gravitation is a completed historical event. This tense correctly describes what Newton did. - Option 4: Discovering
This is a present participle or gerund. It cannot function as the main verb in this sentence without auxiliary verbs. For example, "Newton was discovering..." or "Newton is discovering..." or used as a noun or adjective. Alone, "Discovering" does not form a complete sentence describing a past action by Newton.
Based on the analysis, the simple past tense verb "discovered" is the correct choice to complete the sentence and accurately describe the action performed by Newton regarding the laws of gravitation.
The completed sentence is: Newton discovered the laws of gravitation.
| Option | Verb Form | Analysis | Correctness |
|---|---|---|---|
| 1 | was discovered | Passive voice, implies Newton was discovered, not that he discovered something. | Incorrect |
| 2 | had discovered | Past perfect, usually used for action before another past action. Less appropriate for a single historical event here. | Incorrect |
| 3 | discovered | Simple past, correctly describes a completed action by Newton in the past. | Correct |
| 4 | Discovering | Present participle/gerund, cannot be the main verb in this structure. | Incorrect |
Revision Table: Simple Past Tense
The simple past tense is used to describe actions that happened and were completed at a specific point in the past. It is formed by using the base form of the verb plus "-ed" for regular verbs (like discover → discovered) or using the specific past tense form for irregular verbs.
- Structure: Subject + Verb (simple past form) + Object/Complement
- Example: Newton discovered the laws. (Subject: Newton, Verb: discovered, Object: the laws)
- Usage: Used for single past events, habits in the past, or series of completed past actions.
Additional Information: Newton and the Laws of Gravitation
Sir Isaac Newton (1642-1727) was an English mathematician, physicist, astronomer, theologian, and author widely recognised as one of the greatest mathematicians and physicists of all time. Among his many contributions, Newton formulated the laws of motion and the law of universal gravitation in his work 'Philosophiæ Naturalis Principia Mathematica' (Mathematical Principles of Natural Philosophy), first published in 1687. His work explained the motion of planets and objects on Earth using consistent physical principles. The sentence "Newton discovered the laws of gravitation" refers to this foundational scientific achievement.
