Unformatted text preview: What you can do so far can generate and interpret graphs of AND write equa9ons describing displacement/velocity/ accelera9on vs. 9me graphs What you will be able to do a@er today what a restoring force is why a system oscillates Explain displacement of a spring from Hookes law elas9c poten9al energy for a spring/mass system Calculate conserva9on of energy to SHM Apply x ( t ) = A cos( ! t + " ) simple harmonic oscillator A 2 4 6 y x B Ladybug B had a DIFFERENT ini9al phase constant, = /2 = 0 A = amplitude [m] = angualr frequency [rad] t = 9me [s] = ini9al phase constant [rad] The graph shows the displacement of a mass undergoing simple harmonic mo9on at the end of a spring. Use the informa9on in the graph to write an equa9on for the mo9on of the mass. worksheet General equa9on: x(t) = A cos (t + ) worksheet: displacement graph +/3 OR /3 PICK ANY POINT on the graph AND CHECK!...
