Reflection from learning outcome
Reflection:
What i learned about in this chapter is vectors,(magnitudes and directions), vector kinematics in two dimentions, vector
dynamics as well as motions, forces, velocity and scalar (magntude only). What i found that i have difficulties about this chapter is projectile motion in two dimensions, because the applied equations often confused me with the graphs, and
the questions. I cant figure it out which symbol is which, and which equations is supposed to be used . my strength and weakness is often reading and actually understanding the questions.
Our topic,''How are the principles of projetile motion applied in a sport?'' is related and relevant to daily life, because many sports involves throwing, and estimateing distance, the vertical and horizontal velocity is considered. In this chapter we have not yet included the air resistance but the distance, the angle thrown, the height and the force can determine the magnitude. Monica~~

Reflection by Kira liang:
In this chapter, I learned the relative velocity, the two-dimensional kinematics and projectile motion. I found out that this whole
chapter is difficult to me, especially the projectile motion part. When I was solving questions, I always confused that which formula should I use. The two written questions about projectile motion ( a projectile is launched ) in the test were hard to me. Even I chose the right formula and plugged all the numbers in it, I still could not calculate out the correct answers. Moreover in the retest, I had no idea how to solve for the questions of height.
