## reflection paper

Hi, I Am Nicholas Gilmore, and this is my reflection. let's begin,The Steps That were in my rube were an inclined plane, pulley, and wheel and axle. The inclined plane is about 80 percent of my rube, the pulley like step is at the beginning of the rube, then the wedge was Elisa's finger pulling the marble out. There were 3 principles involved in my rube, and they were kinetic energy, potential energy, and speed. Kinetic energy was used throughout the rube, kinetic and potential energy is with my inclined plane.

Well, the answer is 0.034335 joules, this is how you get the answer. Since the mass is in grams, you convert it into kilograms. And now it should be 0.007 kilograms, now, you change the 50 centimeters to 0.5 meters. Then you do the algebraic equation known as M*g*H=joules.The answer is .0070875 joules. This is because Of the equation KE=.5MV squared. And also you need to follow this equation with the information that the velocity is 45cm/s, and the mass is 0.7 grams.

In conclusion, the design process I went through was Ideas, creativity, then action. With my rube, I had an idea, used my idea of creativity and put it into action. That was my design process. I used critical thinking in my tube because it kept falling apart. My greatest improvement was creativity but that was a different story
