Simple Harmonic Motion and Elastic Energy
... Hooke’s law gives the force exerted by a spring that is stretched or compressed beyond the equilibrium position. The force is proportional in magnitude to the displacement from the equilibrium position. Simple Harmonic Motion as exhibited by the mass spring system is one form of periodic motion. The ...

Newton`s First Law of Motion
... in Newtons, multiply the number of kilograms by 9.8 • If you know the weight in Newtons, divide by 9.8 and you’ll have the mass in kilograms • On earth the acceleration due to gravity is 9.8 m/s2 – That is g = 9.8 m/s2 – One kilogram of nails weighs 9.8 Newtons, which is equal to 2.2 pounds – Away f ...
