As a ball falls under the influence of gravity, does gravity do positive work or negative work? Provide a mathematical explanation. 4. Set up the preceding problem starting from the definition of work as a path integral (with two vectors under the integral with a dot product), and evaluate it showing all steps. Assume the box falls from height h; to hf where hi > hf.
