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.
