The Force
is Strong in me.
FORCES, we have been studying forces for a while now. We
have been mostly focusing on “contact forces” (objects touching) such as normal
force and tension force. As we were
starting this unit I felt really scared because “Forces” are really difficult
but my friend Isaac Newton created 3 simple laws for me to follow; to pass this
course.
1. “Every object
in a state of uniform motion tends to remain in that state of motion unless an
external force is applied to it”
2. “The
relationship between an object’s mass (e), its acceleration (angle), and the
applied force (fa) is f=ma. Acceleration and force are vectors; in this law the
direction of the force vector is the same as the direction of the acceleration
vector.”
3. “For every
action there is an equal and opposite reaction.”
When I was solving a problem I would always have these laws
in my head. The first thing I did when I tried to solve problems was to apply
these laws and draw a labeled free body-diagram (LFBD). Even using these
techniques I still found quite difficult to solve problems with Acceleration. I
much prefer problems that are in Equilibrium.
When Mr. Law came to our class I found it really interesting
when he “actually” should us the problems. What I mean by “actually”, is that
he would shows us how a particular physics situation works using real life
material other than diagrams. For example if the question was about a wooden
slope and a wooden block sliding down it he would take a piece of wood create a
slope out of it and take a wooden block and place it on the block. We this we
are able to see the situation in real time unlike if we drew a diagram and
tried to imagine it moving with all the forces. I found this to be a different
technique of teaching that most of my physics teachers never use.
I am “The One who will bring balance to the Force”
We started studying force situation that were in
Equilibrium. At first this unit did not click. But surprisingly by the end I
felt pretty comfortable with this unit. I don’t know how this happened but it
just did. I somehow figured how to do almost every single question. To be
honest I was doing all the questions but then I just fell asleep. When I woke
up,(the day of the test) I thought I was “toast” but somehow I was able to do
almost every question. It is all a mystery; how did I do it?
You sure know ur physics Jed!
ReplyDeleteVery interesting how you brought up Newton's laws. I simply talked about the topic we faced, but I like your application of them. Awesome stuff! I wish I talked about it in my reflection
