[Active Figure 3]
Covers chapter 3; 2-D motion, projectile motion, and relative velocity. Ch.3: pp.59-79 HW02
Solutions 01

Feb. 5 Lecture 5: Forces
[Movie 1]
Covers the beginning of chapter 4. Introduction of Forces and Newton's First and Second Laws. Ch.4: pp.87-94 Intro: 1D Motion
Feb. 7 Lecture 6: Newton's Laws
Review of Newton's First and Second Law (F=ma) and introduction of Newton's Third Law (action-reaction force pairs) and the Gravitational Force. Ch.4: pp.87-100 HW03
Solutions 02

Feb. 12 Lecture 7: Newton's Laws & Friction
[Active Figure 4]
[Active Figure 5]
Applications of Newton's Laws and Free Body Diagrams. Introduction of a model for friction (static and kinetic). Ch.4: pp.100-123 1-D Motion
Feb. 14 Lecture 8: Circular Motion
[Active Figure 6]
[Active Figure 7]
Introduces the angular versions of position, velocity and acceleration, and centripetal acceleration. Discussion of Gravity and planetary motion; much of Newton's original work was inspired by an effort to understand the motion of planets and explain Kepler's Laws. Ch.5: pp. 135-154 HW04
Solutions 03

Feb. 19 Lecture 9: Work
[Active Figure 8]
[Active Figure 9]
Begins chapter 6 by introducing Work, Kinetic Energy, and the Work-Kinetic Energy Theorem. Discusses Potential energy and conservative forces (those for which the concept of potential energy is applicable). Ch.6: pp.160-173 1-D Motion
Feb. 21 Lecture 10: Conservation of Energy
[Active Figure 10]
Conservation of energy is one of the most important concepts in all of physics. In this lecture we define Mechanical Energy as the sum of Kinetic and Potential energy and study the problems for which conservation of mechanical energy allows for easy solutions. We also explore the changes in mechanical energy induced by non-conservative forces. Ch.6: pp.173-178 No HW
Solutions 04

Feb. 26 Midterm Exam 1 Covers Chapters 1-5

Test Sample
Feb. 28 Lecture 11: Power
[Active Figure 11]
Covers the concept of power, which describes how quickly work is being done. Also discusses the work done by varying forces. Ch.6: pp.179-186 HW05
No Solutions

March 4 Lecture 12: Momentum and Impulse
[Active Figure 12]
Introduces the concept and momentum conservation. The conservation of momentum is more generally true than the conservation of mechanical energy and extremely important for understanding collisions between objects. Ch.7: pp.196-205 Forces
March 6 Lecture 13: Collisions
[Active Figure 13]
[Active Figure 14]
Reviews the concept of momentum conservation, and applies it to elastic and inelastic collisions in 1-D and 2-D. An interesting example of how physics governs the game of pool is given. Rocket propulsion is also introduced. Ch.7: pp.205-215 HW06
Solutions 05
