Homework Help Overview

The discussion revolves around understanding the differences and relationships between Newton's 2nd and 3rd laws of motion. The original poster seeks clarification on how these laws apply, particularly in the context of force and acceleration.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the relationship between the two laws, questioning how the application of force relates to the forces exerted by objects. There is also a discussion about which law is more applicable in specific scenarios, such as a rocket in flight.

Discussion Status

The conversation includes differing opinions on the application of the laws, with some participants suggesting that both laws are relevant in the context of a rocket's flight. There is an ongoing exploration of how to differentiate between the two laws in various situations.

Contextual Notes

Participants express confusion regarding the appropriate application of the laws in test scenarios, indicating a need for clearer distinctions between the two concepts.

What is the difference between Newton's 2nd and 3rd law of motion? Are they related as in if I applied force so that an object accelerates, would it exert the same amount of force towards me?

Yes, they would.
 
I can't differentiate which law (best choice) to put on a test, cause I'm confused about the 2nd law and 3rd.
For instance, a rocket up in the air - would the best choice be law 2 or 3?
 
Both are needed for a rocket to fly. Which is the correct answer will depend on what the question is.
