On
Monday classes reviewed potential and kinetic energy with equations
and notes. Last Tuesday classes had an assignment due; it was assigned the
previous Thursday – p.133#1-7. Tuesday we also watched a video and
discussed it – relating car crashes and vehicle safety to principles we’ve
discussed in class, and related Gs of
acceleration to force experienced in car wrecks and other situations,
and yesterday we had notes on various forms of potential energy.
Today in class we
worked a practice worksheet and discussed what happens to Kinetic
energy when velocity of an object changes. If not finished in class today, it's homework and due tomorrow.
New Optional Assignment (discussed in class Monday) Use safercar.gov to research a car you ride in often, and then find a safer car and a more dangerous car from the same model year. Using terms we discussed in class or information you learn on safercar.gov, explain possible reasons for the higher and lower safety ratings. Turn in no later than December 14.
