Ballistic pendulum lab.

    1. The problem statement, all variables and given/known data
    How would doing this experiment in the moom effect the experiment ?

    "the experiment in lunching a ball against a pendulum and making an inelastic collision find the kenitic engergy and the inital velocity"
    2. Relevant equations
    I found all the answers and I assume the experiment in the moon would yield the same kenitic energy " I know the gravety is less but I also assuming the height of the combination would rise higher than the earth therefore balancing the equation"

    earth
    "Vi= ((2*9.81*.0821)square-root )
    Vi=1.27m/s

    moon " assuming the gravity is half the earth (4.905m/s^2) and therefore assuming the pendullum is will go twice as height (.1642m)

    Vi=((2*4.905*.1642)square-root)
    Vi=1.27m/s

    "I said the experiment being done in the moom with the same materials use in the earth would give the same Vi because less gravety would balance with higher "H" height.

    that's my answer make sense

    thank you! very much

    Your intuition is correct. The actual collision is exactly the same. The difference would be in the height to witch the pendulum would swing.
