The pendulum shows elastic collision and conserved momentum. In this set up, no momentum is actually lost. Ball 0 just transfers its momentum to stationary ball 1 which it collides with(head-on collision) so ball 0 is put to stop then ball 1 collides with ball 2 causing ball 1 to stop and transfer its momentum to ball 2 and so on until the momentum gets transferred to ball 4 then ball 3 collides with ball 2 and the cycle continues.
Thoughts on KPUP Grading System
As we all know, the new KPUP grading system is composed of four different parts: Knowledge, Process, Understanding, and Performance. Knowledge covers the facts and information taught. Process tests how students assess or process the knowledge taught to them. Understanding is how the students understand and explain the lesson after processing it. Performance is the product or outputs of the students. As changes are added, we should expect some effects as well. Being a second year high school student myself, I have experienced the good and bad sides of this grading system.
First of all, it had a good effect on the students in terms of giving effort in academics. Why? The answer is simple. All the graded seat works, quizzes, and long tests are now called assessments, and therefore they carry the same weight in terms of grading. This will enable students to study more and be more conscious about their grades.
On the other hand, it may also affect many people like me. Since seat works are given to students very often and they weigh a big part of our grades, it tends to stress the students out because it is just like having a quiz every other day. Another thing is that the process and understanding parts of the assessments can be subjective to some people. It did not affect me directly, but it did to some of my classmates. It is hard to get a concrete answer to those questions because not everyone has the same opinion and way of processing knowledge on a certain topic....
