```Physics 2050 – Spring 2016
Physics for Scientists and Engineers, 9th ed., Serway and Jewett
CHAPTER REVIEWS
Chap. 1:
PHYSICS AND MEASUREMENT
-Units: MKS, CGS, British (length, mass, time)
-Dimensional Analysis
-Conversion of units
-Significant Figures
Chap. 2:
MOTION IN ONE DIMENSION
-Displacement
-Average velocity (and graphical interpretation)
-Instantaneous velocity: graphical interpretation  limit as t0 of avg. velocity = dx/dt
-Average acceleration
-Instantaneous acceleration: limit as t0 of average acceleration = dv/dt
-Motion with constant acceleration  4 kinematic equations (Eqs. 2.13, 2.15, 2.16, 2.17)
-Freely falling objects: const. accel.  kin. eqs. with a = g= 9.8 m/s2 = 32 ft/s2
Chap. 3:
VECTORS
-Coordinate systems
-Vector and scalar quantities
-Properties of vectors: addition, subtraction, negatives and multiplication by scalars
-Components of a vector, magnitude, angle and unit vectors
Chap. 4:
MOTION IN TWO DIMENSIONS
-Position, velocity and acceleration in two dimensions: same as one dimension, but they are
vectors
-Two-dimensional motion with constant acceleration: same as one dimension, but with
components in both directions, the motion in the two directions is independent
-Projectile motion: horizontal and vertical motions are independent
(horizontal: a = 0; vertical: a = g = 9.8 m/s2)  kinematic equations apply
-Uniform circular motion: radial (centripetal) acceleration = ac = v2/r; tangential acceleration
= at = change in magnitude of velocity (speed) with time
-Relative velocity and acceleration: rac = rab + vbct; vac = vab + vbc; aac = aab
