    I'm finding change in weight due to vertical forces, and I have the following readings:



    Original weight 150±4 N
    Final weight 110
    ±9.4N

    How do I combine them to find overall change in weight?
    Thanks.

    There is a sticky thread at the top of this forum all about combining errors like this.

    It's here

    Your answer:

    Subtract the weights to find the difference.
    Add the uncertainties to find the total uncertainty.

    I suggest you take a look at the sticky thread.
