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 https://mazzudesign.com

WebThen if an object is moving across a surface to the right, the friction force should be negative (acting against the positive applied force), and the normal force should be positive (acting against the gravitational force). Let's say: F N = 882 N and μ = 0.600, then: F f = 0.600 × 822 = 529 N, which is positive, when it should be negative. floating kitchen shelves for microwaveWebNov 8, 2024 · On the other side of the plot when the spring is compressed, slope is negative, giving us a force pointing toward +y direction, which is where the equilibrium is and toward lower values of PE sm.
