Applied Maths: Collisions Applets
| Collisions: Two dimensional (higher level) | Both of these applets are similar - can't say I quite understand everything . . . | 3 Star | |
| but useful nonetheless | 3 Star | ||
| This one allows for slightly more interactivity | 4 Star | ||
Re-distribution of momentum experienced in road collision |
From a lecture given by Dr Kevin McGuigan for the IOP. Moves on to friction after. |
||
Momentum experienced by an astronaut (cartoon): |
While you're there check out all the other examples
listed on the left hand side |
||
Consevation of momentum |
The most realistic of the applets on this topic, but limited to five minutes per day |
||
Useful for showing elastic and inelastic collisions |

Everything you need to know about water rockets |
Including how to make them |

Newton's Cradle Applet |

Or see a video clip of it, together with a little
bit more analysis |
If 1 ball goes in, why can't 2 balls go out with half the initial speed? |
