Hooke’s Law The Restoring Force of an ideal spring ( ) is equal the product between the Spring Consta t ( ) and x F to the product between the Spring Constant ( ) and the Displacement ( ) of the spring from its equilibrium k x position. conservative force x F k x = − The minus sign indicates opposite direction. Simple Harmonic Motion The Graph of Position versus Time for an object in imple Harmonic Motion has a (co)sinusoi al shape. Simple Harmonic Motion has a (co)sinusoidal shape. Helpful Model – Reference Circle The Graph of Position versus Time for an object on Reference Circle also has a (co)sinuso al shape. a Reference Circle also has a (co)sinusoidal shape.
