hello ppl. .
i am working on a simulation for this newton's cradle. .
i want to make the simulation myself
but i like to get use of this cute simulation in here. .
so may u please put here a full physical study for newton's cradle. . so that i can start working on the simulation. .
thanx alot . .
Download the jar
Inside the folders there should be the java file.
I think you should be able to figure out the equations from the open sourced xml or java, do your own homework ;)
In a Newton's Cradle , hard steel spheres hang at rest side by side. If one or more of the spheres is displaced and released , near elastic collisions ensue. http://www.egglescliffe.org.uk/physics/physicists/newton/nlaws/collision.html
* Spheres are perfectly smooth
* Collisions are head on.
* Energy is purely translational and not rotational or vibrational
*[s] Collisions are perfectly elastic[/s]
