Do you know the mass of your vehicle? Bring it to class to find out! I will post the rubric for the essay by tomorrow. The essay is due when you get back from vacation. Great job building and rebuilding your vehicles. Engineering is hard work!

12-13 12:20pm

Go to work and power questions in student resources and complete the assignment.

Dec 3 and in class Tuesday

You can start this at home. You have all of class on tuesday to try to finish. You are not required to hand it in for a grade. You can work on it with someone if you are having trouble. Show all your work and we will go over it on Wednesday. Try the problems on your own and then check for the correct answer and solution using the guided solution links.

Super job on the final everyone! Essay: Bring to class on Monday with the rubric scored and the essay underlined everywhere you got a point. For those of you that have still to do the essay I will place it here for you to read and make sure you answered all the parts. 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 Also read 'The law of Conservation' on the Physics Classroom web page we looked at today in class. We will learn to do problems on Monday.

problem set

You must finish all the problems, as many of you did not do most of the problems.
