Test #4 will be over Chapters 4 and 6
Chapter 4 : Energy
-Formulas :
KE = 1/2 ( mv2 ) ----- *Note: speed and velocity are the same thing; only velocity is squared
GPE = mgh ----- *Note: g = acceleration due to gravity = 9.8 m/s2
ME = KE + PE
Chapter 6 : Thermal Energy
-Formulas :
Q = (m)(Δt)(Cp) -----*Note: t = temperature NOT time in this equation
-Vocabulary :
Conduction : transfer of thermal energy through matter by direct contact of particles
Convection : transfer of thermal energy by the motion of heated particles in a fluid ( includes liquids and gases )
Radiation : Energy transfer by electromagnetic waves
