Kinetic energy and conservation of energy go together?

Click For Summary

Discussion Overview

The discussion revolves around the relationships between Newton's laws, mass, acceleration, impulse, collisions (both elastic and inelastic), momentum, kinetic energy, and the conservation of energy. Participants explore how these concepts interconnect in physical interactions, seeking definitions and clarifications.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Homework-related

Main Points Raised

  • One participant asks how various physical concepts, including kinetic energy and conservation of energy, relate to each other.
  • Another participant requests a more specific question to avoid an overwhelming response.
  • Definitions of concepts such as Newton's third law, mass, and impulse are suggested as a starting point for the discussion.
  • A participant begins to define Newton's third law, emphasizing the principle of action and reaction, and mentions the concept of impulse.
  • Mass is described as a measurement related to the force experienced from a body divided by the acceleration due to gravity.
  • Participants express a need for more focused questions to facilitate clearer answers.

Areas of Agreement / Disagreement

Participants generally agree on the need for definitions and a more focused discussion, but there is no consensus on how to proceed with the broader topic initially presented.

Contextual Notes

The discussion lacks specific definitions for several terms and concepts, and participants have not yet resolved how to effectively narrow down the extensive range of topics introduced.

Who May Find This Useful

Individuals interested in understanding the foundational concepts of physics, particularly those related to motion and energy, may find this discussion beneficial.

How do Newton's third law, mass, acceleration, impulse, inelastic and elastic collisions, momentum, conservation of momentum, kinetic energy and conservation of energy go together?

can you specify a bit? because else i can write it all down for you but that would take quite a few hours.

What do you mean by specify?

I could tell you about:
[tex] F = ma[/tex]
or
[tex] p = mv[/tex]
or
[tex] m_1v_1=m_2v_2[/tex]
or
[tex] (mv^2)/2[/tex]

or any other formula or relationship. If i were to go over everything (as the thing you asked for covers a lot) it wouls take a huge amount of time. Can you make your question a bit...smaller so that it does cover so much?

I'll try...

What I am looking for, is how these things are used in physical interactions.
 
Ok i see. So you are basically looking for definition of those?
 
I think the definitions would be good.
 
ok, i'll give it a shoot

(posting this reply to keep people from replying b4 I'm done since it is a lot to write)
 
Newton's third law of motion:

As the name sounds it is the third law of motion made up by Issac Newton. Its definition is:

"Every action has an equal and opposite re-action"

So if you shot with a pistol, the gun will apply a force on the bullet making it fly away. You will feel a recoil from the weapon. If you try to pull a spring the spring will try to pull back. If you hit a ball, the ball also affects your hand with the same force but in exactly the opposite direction. This also aplies for impulse which i'll come to later.

Mass:

Mass is a measurement that tells you how much force you feel from a body divided by acceleration of gravity.

Now I'm to tired to define the rest in this post. Will try more tomorrow.

you can also try google:

type in

define: impulse

and you will have clear defination of what it is. then try the rest aswell
