Length Contraction L=gL; carefully define each L
Space-time diagram
Pole-barn paradox
Simultaneity Space-time diagram
Causality, timeline vs. spacelike separation, light cone
Lorentz Transformation
Kinematics
Velocity Instantaneous
vs average, 
Vector components
Graphs, x vs t, v vs t, a vs t

Vector components
1D Kinematics Constant
acceleration 
, 
2D Kinematics Vector equations: separate x and y parts.
Gravity: 
Landing: y=0, Meeting: x1=x2 and y1=y2 at same time
Y=0 problems: symmetric trajectory, Vytop=0, t = 2tdown =2tup
Yf=h problems: quadratic equation
Separate physics from math
Eeyore drop problem
Uniform
Circular Motion 
, direction toward center
X=rcos(wt), y=rsin(wt)
Newton’s Laws
Newton I Inertia, constant velocity unless a net force
Newton II 
Newton III Pairs act on different objects, pairs
Free Body Diagrams Only forces acting ON the object
Forces: Fundamental vs. derived
Gravity: -g at surface of earth
Normal: any direction, kept from entering other object
Tension, spring
