Reflection Paper On Acceleration Of Gravity

980 Words 4 Pages
According to Instructor: Joao Ricardo in the Physics class that I attended on Tuesday and Thursday, the teacher passed a paper for students and the students checked their attendance by themselves and wrote their names and signed on the paper. Then, he had graded the mastery test and gave them back to students to look at the feedback given by the instructor. After one hour, he took the mastery test’s sheets to keep them as students’ records. He also had graded the big test about light.

In addition, he explained the new topic about acceleration of gravity, which is the acceleration of a freely falling body. Free falling means to drop vertically with no air resistance and an acceleration that doesn 't change, or that is constant, all small
If we dropped them from the same height, we can really just compare the time it takes these two objects to fall. Drop one of the objects and record the time. Next drop the other mass object and record the time. Calculate the standard error and the average and use this data to compare the accelerations (time) of falling objects of different mass.

Also, he wrote kinematic equations on the board and gave them 5 questions about distance, speed, time, and acceleration to be answered in the rest of the class by them for extra credits. After students has finished, the teacher tried to review and answer questions verbally to verify that they were really testing the material he wanted to test, and to think about possible alternative answers that might come up. He told them if they still have the wrong answers, you could try again. Finally, students submitted their homework about acceleration’ exercises on their
He divided the class into 3 groups and asked each group of students to search in 3 different sources about the meaning of force and give 5 examples of the force in 15 minutes. They interacted with each other, shared, communicated, and discussed with each other. Then, each group presented the information written in front of the class on the board. Then, the teacher used a lot of examples to distinguish between force and not force. He also explained and more discussed in details the different types of individual forces resulted from the contact of the two interacting objects such as normal force, spring force, and non-contact of the two interacting objects such as gravity force, also known as weight of the object. He emphasized that students have misconception about mass and weight, and they are different. The mass of an object refers to the amount of matter that is contained by the object; the weight of an object is the force of gravity acting upon that object. Mass is related to how much stuff is there and weight is related to the pull of the Earth (or any other planet) upon that stuff. The mass of an object (measured in kg) will be the same no matter where in the universe that object is located. Mass is never altered by location, the pull of gravity, speed or even the existence of other

In the beginning of the semester in the physics course, we were asked to write an essay on what it means to be a learner in physics. I wrote about the importance of being a good listener. I then discussed the importance of being prepared for class and coming in with a willingness to learn, as well as starting class with an open mind to learning outside one’s comfort zone and taking risks. Amongst a few other things, I mentioned that becoming a successful learner requires effort and dedication. These…

Physics can be intimidating, and people often want to know about the prerequisites to start learning physics. All you really need is an open mind, a desire to learn, and a willingness to accept that 90% of what you thought about the universe might be wrong. We all know we have a lot of development that has not yet been answered so that is why we need to study physics. As a sailor it has a big help to us someday because we can apply physic in our daily lives. It is not easy to study physics, but…
