7. one point, from Lecture 7, a group question, involves some equations, mostly words

(a) .6 Newton's Laws of Motion. State Newton's three laws in words and equations (if appropriate), and say what each contributes to our understanding of the concept of force without just repeating what the law is. ("Characterize" the three laws.)

(b) .4 Interpreting Newton's 3 Laws. Mechanics is the branch of physics which includes kinematics plus dynamics. What distinguishes dynamics from kinematics? (.1)
What is meant by initial conditions? (.1)
How does the second law imply determinism? Include in your answer what determinism means. (.1)
In a collision, momentum is conserved. How is that statement equivalent to the third law? (.1)
