Reading Assignment:
The reading for Exam 3 is: Tippens: Ch. 4 Sections 1, 2, 3, 8. Ch. 7 Sections
1, 2, 3, 4. You will not need to use trig to solve any of the problems
on the exam. You should review the use of the kinematical equations since
you may need them on the exam.
Exam 3 is, inprinciple, cumulative. However,
most of the exam will be on material covered since the Exam 2. Of greatest
import is to understand Newton's Laws and to be able to apply them to physical
systems. This involves knowing how to identify the important forces acting
on an object, to be able to draw a free-body diagram, to write down Newton's
2nd Lzw accurately for the physical system considered, and to use it to
answer questions about the system -- such as what's the resulting acceleration,
how will the object move under that acceleration and related questions
about tension or the force of friction if relevant.
To study for Exam 3:
- (1) Read the relevant sections of Tippens
and do relevant problems from the back of the chapters. Examples include
the following. Ch. 4: problems 21 and 23 on p. 110. Ch. 7: problems 1,
3, 5, 11, 13, 15, 21, 23, 25, 27, 31, 33 on pages 168-170.
- (2) Read the lecture notes. You should use
the class outline as a guide.
- (3) Review the kinematical equations.
- The exam will be broken into four parts. The
parts are the following: (1) Newton's Laws and Their Implications, (2)
Simple Applications of Newton's Laws, (3) More Simple Applications of Newton's
Laws: Use of Kinematical Equations, and (4) Advanced Applications of Newton's
Laws. Points are distributed as follows: (1) ten four point questions totaling
40 points, (2) two six point questions totaling 12 points, (3) four six
point questions totaling 24 points, and (4) four six point questions totaling
24 points.
- Make sure you study not just how to do quantitative
problems but also understand the problems conceptually.
