    guys
    i need help with this small project.
    i want to alter the weight of an object-ball dynamically using a lever.
    now w=mxg
    mass is constant.how do i change gravity of the ball?
    any suggestions?

    thanks

    Putting the ball into orbit would change the weight of the ball, but how would this change the gravity of the ball ?

    The op was asking about weight in terms of w=mg, g is the acceleration due to the gravity of the earth. That changes with height. If you equate the term "gravity" with the gravitational mass of the ball, then there is nothing that you can do about it. But I don't think that is in the spirit of the original quesiton.

    OK, I do now understand.
