It's all about words and what they really mean.
"Meaning" is itself a fuzzy concept.
The difficulty of physics stems from the fact that many of the words used in physics incorporate concepts that are fuzzy or totally misunderstood by the general public.

Our goal is to eliminate the fuzzy and erroneous and obtain a clear understanding of the words and concepts used in physics.

Specifically:

precision
accuracy
distance
displacement
speed
velocity
acceleration
force
torque
impulse
heat

Let's do some Physics!

Today's Agenda:

1. Take the Force Concepts Pre Test.

2. Take Quiz 0 in groups of 2.

3. Do Experiment 0, determining the value of ¼.
