PHYSICS 109 Chapter Notes - Chapter 11: Simple Harmonic Motion, Phase Angle, Natural Frequency
Document Summary
Oscillatory motion requires elasticity - deformation of objects causing a restoring force. 11 - simple harmonic motion that drives objects back to their equilibrium. Measuring the elongation (stretching) of a spring gives an idea of force -- soft springs stretch and can carry a lot, stiffer springs stretch only a small amount. Mass - the amount of matter an object has. Weight - the amount of matter an object has multiplied by the acceleration force acting upon it. The weight of a human being on earth is different than the weight of a human being on the moon. The mass of the human being on the earth or the moon is always the same. To find the weight of any object on earth, multiply the mass (m) by 9. 8 (g of earth) which will give you the weight of the object in newtons.
