Simple Harmonic Motion
... Vibrating System is Constant KE + PE = constant If the maximum amplitude of the motion is x0 then the energy at any point x is given by: ½ mv2 + ½ kx2 = ½ kx02 From this we can solve for velocity: │v│= √ [(x02 –x2)(k/m)] From Hooke’s law, F = -kx and F =ma, therefore a = -(k/m) x ...

... • air resistance is a form of friction • Sometimes we want to increase friction. (ex: cinder an icy road) • Other times we want to reduce friction. (ex: change your oil) • For ordinary solids, friction is caused mostly by local adhesion between the high spots, or asperities, of contacting surfaces ( ...

... We previously derived equation (4.16) for the linear velocity of a rotating rigid body. We could think, for example, of a solid, rotating disk and focus on the trajectory of a point on its surface. Since this point, which at a given instant has the velocity v , does not move linearly but rotates, th ...
