essay grading

I will post a rubric in the student resources. To the best of your ability, match the statements on the rubric to what you have written. For every statement that you make that is essentially the same as the one in the rubric, underline it in colored pen or pencil, and give yourself the number of points allowed. if it says you can get 1 pt then, give yourself only one point ( you can not have more than one point if you offer two similar or even different statements/examples for each category. There is a maximum of 6 points on the first part (N1 law). There is a maximum of 7 points on the second part (N2 law). There is a maximum of 7 points on the second part (N2 law). There is a maximum of 2 points on the second part (N2 law).

Essay Bring to class and keep with you until the final exam!!! A person has a bow that takes 500N to fully pull back. They have put in the string a 0.1 kg arrow. Define Newton's three laws in terms of the person shooting an arrow. Describe what happens, and why it happens for each of Newton's three laws and the forces of friction ( and any other forces on the arrow). Describe what happens to pull back the string, and the result as you let it go. Also describe what could be done or forces on the arrow that would make the same shot go in three different locations other than the target they aim for. Each idea gets a paragraph,,,example: define Newton's first law...... it applies to the bow and arrow because... The arrow if shot over a target would...because.... define Newtons second law... it applies to the bow and arrow because... The arrow is shot with more _____ then._______...because or if the arrow was twice the mass then...because... define Newtons third law... it applies to the bow and arrow because... The force on the string is on the hand of the archer, and the force........because or the arrow would not go as far if the force...... then...because

Do the forces mass acc' problem set in the student resources. The difficulty of the problems vary. Try your best. Call a friend and discuss the problems if you choose.

NOVEMBER 14

Know the three laws for a matching quiz Review the notes from last night so you can do the problems in class tomorrow.

Read the information at: http://csep10.phys.utk.edu/astr161/lect/history/newton3laws.html search two other web sites for Newton's three laws of motion. Come up with extensive definitions for these three laws and memorize them.

A person throws a ball downwards into the Grand Canyon at an initial speed of 10 m/s. What is the final speed of the ball after 20 seconds? How far would it travel in 20 seconds? If the canyon is 1600 meters deep at that spot, will it hit the ground before the 20 seconds are even up? If you throw a ball up into the air with an initial velocity of 0 m/s, how long will it take until it reaches its highest point? Remember that the acceleration of the ball is now negative because it is pulling the ball down as you throw it up, therefore decreasing its speed every second. Also know at its highest point the ball has a velocity of 0 m/s. A car going down the highway at a constant acceleration of 3.2 m/s2 , travels for 15 seconds. What is the final speed, and what is the distance it travels during that period? Do the questions out in the five step format on a piece of paper and hand it in at the begging of class. If you still don't know how to do these questions, research them online.

We will continue with the test for half an hour of the period. If you are not done by then, plan on staying awhile to finish after school.
