We worked on our graphing skills for the spring-mass system. Graphing the kinetic energy and the spring potential energy was a bit difficult. Also, finding the amplitude of the velocity-time and acceleration-time graphs requires us to go back to all our old models.
We then talked about what restoring force means. For a restoring force situation can happen, the object must be in stable equilibrium. The time the object takes to return to equilibrium depends both on the inertia of the system and the strength of the restoring force.
Oh, we also planned for a taco party tomorrow. The taco sauce that's been in my room for three years expires tomorrow.
