Discussion Overview

The discussion focuses on the effects of bouncing on the force experienced by a wood car with passengers (eggs) when it impacts a cement block at the end of a ramp. Participants explore concepts related to collision types and their implications for force and acceleration during impact.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant describes a scenario involving a wood car and its impact dynamics, questioning how bouncing affects the force experienced during the collision.
  • Another participant asks if others have studied the differences between elastic, inelastic, and plastic collisions, suggesting these concepts are relevant to the discussion.
  • A participant expresses some familiarity with collision types but indicates a lack of understanding regarding their effects, highlighting a need for clarification.
  • One participant proposes a comparison between perfectly elastic and perfectly inelastic collisions, using examples of a steel ball and putty to illustrate differences in speed and acceleration forces during impact.
  • Another participant notes that force is a vector and questions which collision scenario—sticking to a wall versus bouncing back—results in a larger average acceleration, prompting further exploration of the relationship between force and acceleration.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus, as there are multiple competing views regarding the effects of different types of collisions on force and acceleration.

Contextual Notes

The discussion includes assumptions about the nature of collisions and their effects on force, but these assumptions are not fully explored or resolved. The implications of collision types on acceleration and force are also not definitively established.

Who May Find This Useful

Individuals interested in physics, particularly in the areas of mechanics, collision theory, and impact dynamics, may find this discussion relevant.

Situation: A wood car with 2 eggs as passengers goes down a 2.43 meter ramp at 40 degrees. The car has a crumple zone on the front to absorb some impact. If the car bounces when it hit the cement block at the end of the ramp, how will the bouncing affect the force the car experiences on impact?

Have you studied the difference between an elastic, inelastic, and plastic collision?
 
I've studied the different collisions a little, but I still don't understand what affects of the different types of collisions.
 
Lets assume a perfectly elastic collision versus a perfectly inelastic collision (plastic). So a typical example is a steel ball and a round piece of putty both striking a very hard surface.

If you look at the speed over time, and use the same interval for the collision time, what happens in terms of acceleration forces?

We know the steel ball starts at X speed and ends up at X speed, whereas the putty starts at the same X speed and ends up at zero.

Cliff
 
The force is a vector, and is proportional to the acceleration, which is also a vector.

Given that the acceleration is a vector, which system represents a larger average acceleration? A ball hitting a wall and sticking to it, or a ball hitting a wall and bouncing backwards?
