PHYS 100 Introductory Physics Dr. Labroo Study Topics for Exam 2 Chapter 4 A good understanding of the concept of “work”. Simple problems based on the relationship between force, distance and work: Work Force x Distance Power as the rate at which work is done: Power (Force & Distance are parallel or antiparallel) Work Time Energy and its relationship to work. Different forms of energy: Elastic potential energy, Gravitational potential energy and Kinetic energy. Simple problems based on the following: Gravitatio nal Potential Energy Weight x Height 1 Kinetic Energy x (Mass) x (Speed) 2 2 Simple applications of the work – energy theorem and the conservation of energy principle. Chapter 5 Vibration as a periodic motion. Understanding of Time Period and Frequency and the relationship between them: 1 1 Frequency or Time Period Time Period Frequency Wave motion and transfer of energy. Classification of waves as transverse or longitudinal. Understanding of the following wave characteristics: Amplitude, Wavelength, and wave speed. Simple problems based on the following relationship: Speed Frequency x Waveleng th Conceptual understanding of the superposition of waves and how that leads to interference and standing wave pattern.
