Uniformed Motion Notes
The study of motion:
Everything in
the universe is in motion. From the electrons in atoms, to the stars in
the sky. The continents are moving across the surface of the earth, the
buildings sway in the wind, and even your fingernails are growing out
from your fingers. Therefore, understanding motion is a good way to start
toward understanding the way the world works.
In the study of
motion, we will start with the only the most basic forms of motion (uniformed
motion), and for this unit we will deal with (almost exclusively) free
fall rectilinear motion. The study of motion caused by variable forces
will be handled in the next unit.
During this unit,
you will begin to see how scientists study, and describe, the universe
using the help of experimentation, and math. We will be doing a lot of
labs, developing a few concepts, and do a lot of problem solving. In the
end, we will see how Physics can be used to not only describe motion mathematically,
but also to predict the outcome of a situation before it unfolds.
The difference
between displacement and distance, the difference between speed and velocity,
the difference between vector and scaler, will all become clear, and the
importance of knowing these differences will also become clear. You will
have to work with algebra and trig to solve the problems, but the only
math knowledge required upon entry to this course is algebra. You will
have to learn how to work with units in your mathematics, and come out
with the proper units in the answers to all problems.
Before this unit
is over we will have: dropped things, thrown things, and shot things.
We will have measured the velocity and accelerations of them all. We will
be predicting where flying objects will hit the floor or walls. We will
be mathematically calculating angles and speeds so that we can hit objects
flying through the air with other objects flying through the air!!
It should be a
fun unit and a fun semester. Let's get started!
