Unit 3 Work and Machines Reflection

Before we start this unit, I know almost nothing about work and machines. The only thing I know about it that there are simple machines that can help us, but I don’t know how. After this unit, I have learned more about the simple machines.

One major experiment we do in this unit is the inclined plane, which is changing the angle of the inclined plane, and see if distance change, what will happen to the work. For the lab report, I think I can improve on the Criteria Civ, which is commenting on the validity and reliability of your results. I need to explain more.

I like the part about the simple machines, and want to know more about it, because it can help us in real life. I want to know more kinds of simple machine.Also, I want to know the best angle/length of each simple machines, which best mean that using the smallest force.

Our next unit is about energy. Energy is defined as the capacity of a physical system to perform work. It is also a vocabulary we’ve seen in the lsat unit.

GRASP Project Reflection

In this project, we worked in a group of 4, and we can speared the work into four piece. In the presentation, because one of our group mate didn’t come, so we divide the script into 3 parts. I talked about input and output force and real life examples of the inclined plane. My job for writing the lab report was to write the independent and dependent variables, and Cii.

The most challenging part for this project is the time given for the project. Our class started a day later than other classes, but we still need to turn it in for the same time. We try to use our time wisely so we can have more days for writing down the lab report and the presentation.

The part that I enjoy the most in this project is doing the experiment. The tools we used in the experiment is a combo of a pulley and inclined plane. Although it is only a experiment tool, but it is still useful in real life, to lift heavy things up.

For the part that I will remember, I think the part of doing the experiment will be the most memorable. It is very interesting and also important. It is helpful in real life, because it can help us to use less force.
