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. Resonance and the Doppler effect.
