It has been two months since I took physics 12 in
this school. I learnt a lot within these two months. I learned about vector,
kinetics, projectile motion, how to calculate the magnitudes and directions. I
faced some difficulties while i was studying physics. Sometimes, I don’t get
the question and i have a difficult time on drawing the diagram out. Without
the help of diagrams, it is impossible for me to finish the physics question.
Secondly, for substituting the values into the equation, i always mix up the
initial and final velocity. Thirdly, i had difficulties on calculating the
horizontal velocity Vx and vertical velocity Vy.
In order to solve all my problems and have a good
result on the test, I did many questions about velocity, motions kinetics, vector
and magnitude... until i get used to the format of the questions. If I don’t
understand a question, i usually ask my teacher for advises and ways to solve
the problems. After practising for a while, my understanding of questions
improved and can draw diagrams right after reading the question. I can also calculate Vx and Vy
immediately by using cosine, sine or tangent. Finally, my weakness that I have
to improve is lack of understanding of a question and strength is using
formulae to find the results of the questions.
