... The SI unit of force is the Newton (N). 1N = 1 kg-m/s2. In the US, force is measured in pounds. 1.00 lb = 4.448 N and 1.00 N = 0.2248 lb. Robert Hooke (1635 – 1703) found that when a spring is pulled by a force F, it extends proportionally by an amount x. • Hooke’s law: F = -kx • k = spring constant ...
