Unformatted text preview: Physics 7A DLM 8 Overview CG 2.4 Connection between Force and Potential Energy Act-2.4.3 Follow-up of DLM07 FNTs (<30 min) Learning Goals: ¡ Deepen understanding of the relation of force to change in potential with respect to distance ¡ Strengthen ability to switch between graphical representations, physical phenomena, and mathematical representations in the context of various potentials ¡ Deepen understanding of the reasonableness of defining the zero of potential where the particles are sufficiently far apart to be no longer interacting. CG 3.1 The Particle Model of Matter Act-3.1.1 How Particles Interact ( ~ 5 m i n ) Learning Goals: ¡ Appreciate the importance of the ideas in the generic particle of matter and identifying what the four main ideas are ¡ Begin to get comfortable with the graphical representation of a pair-wise particle-particle interaction. ¡ Strengthen understanding of the relation of the nature of the force (repulsive or attractive) to the shape of the pair-wise potential energy curve ¡ Deepen the connection of the graphical representation of the pair-wise potential, the nature of the force, and the physical separation of the two particles Act-3.1.2 The Separation of Particles: Solids—Liquids—Gases (~ 50 min) Learning Goals: ¡ Develop a realistic mental image of the spacing between particles in different phases. ¡ Connect prior experience with real solids, liquids, and gases to the spacing of particles in the particle model of matter. Realize that the interparticle spacing in liquids (and solids) can be...
