Conservation of momentum in explosions.
Many thanks to ukukuku for the excellent series in momentum and collisions.[br]Modified for my own use.

with preset scenerios.
This applet is modified from ukukuku's excellent linear momentum series.

ballistic pendulum question

many thanks to ukukuku for this applet.

example: billiard balls

2D collision is not covered by this physics course. This is just to illustrate that momentum is conserved in 2D as well.

  • 1. Hit of Billiard balls

6.1.

Hit of Billiard balls

[b]Impetus of billiard balls[/b] The material shows the hit of two billiard balls. The parts of the impetus and the direction the ball will go are shown. Move the point Z to give the ball Ks the direction to the ball K1. Dieter Tremel
