Solved QUESTION 1 The slope of the Spring Force v. Position
WebApr 6, 2009 · work done by spring forces -- positive or negative I have gotten the sign wrong on every single spring force-related problem. I'm pretty sure I'm working out the problems correctly, but the answer turns out to be negative when I have it positive, or positive when I have it negative. WebJul 7, 2024 · If x is negative (displacement upwards with the spring being compressed) then F is positive ie the force on the mass is downwards. So the equation F = − k x correctly predicts the direction of the force for a given displacement of the end of the spring. floating kitchen shelves shiplap
