lecture goals

• Understand the foundation of dynamics, the study of the causes of changes in motion, also called forces. This is probably the single most important concept in physics.
• Learn Newton's three laws of motion, or laws of dynamics, or force laws.
• Understand how momentum feeds into the three force laws, all of which can be written in terms of momentum.
• Understand simple examples of the above, especially some fun analyses of human motion and use of forces.
