Physics 101: Lecture 20, Pg 2 Ideal Springs Ideal Springs Hooke’s Law: Hooke’s Law: The force exerted by a spring is proportional to the distance the spring is stretched or compressed from its relaxed position. F X = -k x Where x is the displacement from the relaxed position and k is the constant of proportionality. (often called “spring constant”) relaxed position F X = 0 x x=0
