Today in class we listened to the summaries of the 21st week of news articles. We then discussed section 7-3 & 7-4 notes on work output, work input, mechanical advantage and mechanical efficiency. Students then worked on problems 1 & 2 on page 15-8 with their partner. We showed the solution to those problems on the board.
No homework was assigned.
