Discussion Overview

The discussion revolves around comparing two collision scenarios involving identical cars: one where two cars collide head-on and another where a car crashes into a solid wall. Participants explore the implications of momentum and impulse in determining which situation results in the greatest impact force.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant suggests that the forces are the same in both situations, asserting that the first situation results in a greater impact force due to the opposing velocities of the two cars.
  • Another participant claims that the impulse transfer is larger in the first situation because both cars are moving, while in the second situation, only the car has impulse.
  • A different participant states that the impulse on each car is the same in both situations.
  • A later reply indicates a misunderstanding of the question, suggesting that interpretations may lead to different conclusions about the scenarios.

Areas of Agreement / Disagreement

Participants express differing views on the impact forces and impulse in the two scenarios, indicating that the discussion remains unresolved with multiple competing perspectives.

Contextual Notes

Participants reference concepts of momentum and impulse but do not fully resolve the implications of their definitions or the conditions under which their claims hold true.

2 Situations.
One: Two identical cars crash head on (inelasticly) @ v miles per hour each (in opposide directions of course).
Two: A car identical to those two cards crashes (inelasticly) @ v miles per hour into a brick wall (ie. solid and unmovable... although I have seen pics of a car that just went through a brick wall...).
which of the two situations results in the greatest impact force.

Which answer?
The forces are the same in both.
Hitting the other car (One>Two).

P=momentum
J=impulse

I figure F (impluse; whatever) =delta(P) right? So in the first situation delta P is greater since they have opposing velocites (-P and P).
But if you do P+J=0 then J=P in both cases right?

I'm pretty confused; what's right and why? HElps mes!
 
Physics news on Phys.org
in the first situation the impuls transfert is bigger due to the two moving objects...
in the second situation only the car has impulse p...

maybe this will help...

The impulse on each car is the same in both situations.
 
Ya, I got it now. I sort of misunderstook what was being asked... they are both right depending weather you interpert the question correctly or not :p
