Do Now Weekly Reflection Time Please write about one of the following: Normal recap of how your week was If you went on the college trip, what your least and most favorite parts were Where you want to live when you’re older and why Most embarrassing moment you’ve ever had

Important Dates & Reminders Unit Exam next Thursday! Homework Turn-In February Monthly News Project Extra Credit Monthly News Project Spring Break Kickoff Dance

This is time to brainstorm ideas for what to accomplish the week before spring break Quick Brainstorm

Pendulums When does this pendulum have only potential energy? When does it have only kinetic energy?

Pendulums The energy switches back and forth between these two types of mechanical energy but TOTAL mechanical energy always stays constant

This short video gives an overview of Law of Conservation of Energy related to pendulums Video Recap

Check for Understanding As the pendulum swings from position A to position B, what happens to its potential energy? A. A.Decrease B. B.Increase C. C.Remain Constant

Check for Understanding As the pendulum swings from position A to position B, what happens to its kinetic energy? A. A.Decrease B. B.Increase C. C.Remain Constant

Check for Understanding As the pendulum swings from position A to position B, what happens to its total mechanical energy? A. A.Decrease B. B.Increase C. C.Remain Constant

Check for Understanding Which statement is true about this swinging pendulum? A. A.The potential energy at A equals the kinetic energy at C. B. B.The potential energy at A equals the kinetic energy at B. C. C.The speed of the pendulum at A equals the speed of the pendulum at B. D. D.The potential energy at B equals the potential energy at C.

Check for Understanding If a pendulum is displaced, giving it a potential energy of 5 J, what will be the maximum kinetic energy it attains? A.0 J B.2 J C.2.5 J D.5 J
