(Probable) Exam #1 Topics

Relativity

Galilean Transformation

Inertial Reference Frame                Clock Synchronization

Light Clock

Time Dilation                            t=gt; carefully define each t

Space-time diagram

Length Contraction                    L=gL;   carefully define each L

Space-time diagram

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

Acceleration                                Instantaneous vs average,

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

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
