The Physics Journalist On Tuesday December 2 students in Mr. Manning's Physics class did the following: 1) Homework (pg. 8) check and Review 2) Daily Questions 3) Finished Reviewing pg 6 and 7 4) More Review 5) Test/Reading Guide/ Protractor reminder


 * Pg 9 was handed out as a review aid for Wednesday's Test on Newton's Third Law

Today mostly consisted of a review of scenarios concerning Newton's 3rd Law and there were a number of key ideas established. Cory Miller and Annie pushed on each other to prove to the class a point. Cory stood on paper towels during the demonstration and he was pushed away from Annie. Cory's lower coefficient of friction caused him to be thrust backwards. A game of tug o' war was considered to compare the forces. It was determined that whoever has the most amount of friction will win the tug o' war. The person that exerts the most amount of force to the ground will win.

Another example was two 100 N weights hung on off of a force scale, one on the hook and the other holding the force scale in place. It was found that the force reading is 100 N.

In a final theoretical scenario two people pulled on a rope on top of frictionless ice. The equally massed people pulled on the rope with the same amount of force( Newton Third Law) so they both accelerated equally. They also met in the center of the rope.

Do not forget a protractor.
