Homework Help Overview

The discussion revolves around the concept of impulse in the context of car crash safety. Participants are exploring the implications of impulse size and duration during a collision.

Discussion Character

  • Exploratory, Conceptual clarification

Approaches and Questions Raised

  • Participants are questioning whether a larger or smaller impulse is safer in a car crash and discussing the relationship between impulse duration and safety. There is an exploration of how impulse relates to changes in velocity and momentum during a crash.

Discussion Status

The conversation is ongoing, with participants providing insights and clarifications about the nature of impulse and its effects during a crash. Some guidance has been offered regarding the relationship between impulse duration and safety, but no consensus has been reached.

Contextual Notes

There appears to be some confusion regarding the definitions and implications of impulse, particularly in relation to the duration of impact and changes in momentum.

I have an easy question about Impulse [tex]J[/tex]: Is it safer in a car crash to have a bigger impulse or a smaller impulse?
 
Physics news on Phys.org
What does your instinct say?And why?


Daniel.
 
i want the crash to take place over as long a period of time as possibe.
 
It doesn't really work that way.Usually the time of impact (the time in which momentum is being transfered) is rather small,making the effects even larger...

The only way to have a smaller impulse is to have a smaller change in velocity. Perhaps you mean: for a given crash impulse, or change in momentum, is it safer to have to have a longer or shorter duration for that impulse?
