    How do you find the inertia of an object? i googled it and it just confused me, can you help? plzzzz

    like an example is an ice skate weighing 180LBS skating at 10mph, what would be the inertia of the skater

    What object are you measuring?

    You must realize inertia are forces acting upon an object, affecting its outcome. Its like saying the inertia of me throwing a baseball is gravity, air friction, wind, etc.. There's no specific way to measure it. You see what its variables are, and then measure those appropriately. (eg force by newtons/ pull of gravity/ wind speed /humidity - all this on a moving baseball)

    Hope I could help

    Depends what it weighs, 180 what?

    I don't know what it is either, just a unit might help whoever does know.

    well im doing a science project and i want to do it on checking people in nhl 09, and inertia is the onlything that i can think of that would go along with it, but if you come up with any other way i can relate it to checking people in hockey id luv u!!!!!

    Well you're trying to figure out the forces acting upon it. Try to broaden your answers when you say that. I can only think of some when I say this:

    Gravity - you can say 1.08 g's or whatever , a single G is 9.80665 m/s2 (earth's gravity)
    Weight - 180 lbs of force (you will have to do more research on this, its not really 180 lbs of force), convert to kg(metric) then convert to newtons
    Temperature - being cold affects performance of the skater
    sub:
    * Ice's condition
    *Skater's energy

    figure out the rest, shouldn't be too hard.

    Suggestions for project:

    I'll help you out here, using variables.

    (very simple example here)
    Player A uses Entity A. Performance is directly proportional to Player A using/doing Entity A. Is performance increased if Player A tries using/doing Entity B?

    example: Player A = Wayne Gretsky (spellcheck)
    Entity A = Gatorade
    Entity B = Powerade
