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
