The Impulse Calculator will calculate:

- Impulse of an object when colliding to an unmoveable obstacle if the collision time is given
- Force of collision when an object hits an unmoveable obstacle if the collision time is given

The impulse of an object when hitting an unmoveable obstacle J |

The force of collision when an object hits an unmoveable obstacle is N |

Impulse of object calculation |
---|

J⃗ = m × v⃗_{0} - m × v⃗J ⃗ = × - × J ⃗ = |

Force of collision calculation |

F⃗ = m × v ⃗_{0} - m × v⃗/∆tF ⃗ = × - × /F ⃗ = /F ⃗ = |

Impulse Calculator Input Values |

Mass of object (m_{1}) kg |

Velocity of object before collision (v⃗_{0}) m/s |

Velocity of object after collision (v⃗) m/s |

Time of collision (Δt) s |

Please note that the formula for each calculation along with detailed calculations are available below. As you enter the specific factors of each impulse calculation, the Impulse Calculator will automatically calculate the results and update the Physics formula elements with each element of the impulse calculation. You can then email or print this impulse calculation as required for later use.

When calculating the impulse of an object when hitting an unmoveable obstacle a positive number indicates movement to the right.

J*⃗* = m × v*⃗*_{0} - m × v*⃗*

You can calculate the force of collision when an object hits an unmoveable obstacle if the collision interval is available using the following equation:

F*⃗* = *m × v **⃗*_{0} - m × v*⃗**/**∆t*
