# Physics

Ms. Chase teaches Physics at Mass Academy. We are given a
choice to take algebra-based or calculus-based physics. Concepts
taught apply to both tracks, but on tests there is a choice of
whether to do an algebra-based or a calculus-based problem. We have
finished Kinematics, Dynamics, Forces, and Energy and Momentum and
are now moving on to Rotational Movement. This class is fast paced
and covers the AP Physics curriculum.

## Kinematics Lab

This lab was designed to obtain empircal evidence for formulas
that we used in class. We tracked the velocity of a battery powered
car on a flat surface and a freely moving cart down a ramp. We then
then observed trends in data. We expected the battery powered car to
travel at constant velocity and the cart to travel with constant
acceleration. The data reflected these trends.

## Dynamics Lab

This assignment allowed us to be creative and design our own
experiment. Our group decided to see if the coefficient of friction
changed with the orientation of an object. When we analyzed the data,
we got a very significant difference in the coefficients of friction.
We tried a simpler version of the experiment on level ground and
discovered that the blocks we were sliding tended to lean forward as
they had a very high coefficient of friction. This was a potential
source of error in our experiment.
