Many people find writing the goals and objectives section of a grant proposal the most difficult.
In other cases, the problem stems form writing objectives that are too vague. A goal is an end result and should be written in broad and general terms. It is what you expect the situation will be at the end of the project and should express the project's ultimate aim or purpose. In many cases, the project will have only one goal. Funders want to fund projects, not pieces of equipment.
