10/2 Class

Today class started out with Dr. Ezrailson catching us up on what we need to be including in our blog reflections, and she also talked about students who still need to make their blogs. Also, it was stressed that everyone needs to attend class, especially when we have not had face-to-face class in a while. If anyone had any questions about the blogs or anything else, this was the time to ask. Next, we had a lesson on Newton's Second Law, which, according to our textbook, states "The acceleration produced by a net force on an object is directly proportional to the net force, is in the same direction as the force, and is inversely proportional to the mass of the object." We discussed the formula, which is a=f/m. I also learned that gravity on earth is 9.8m/s squared. We were given an example about standing next to an open fire for the concept of the Inverse Square Law (1/r squared). We also looked at a cannon ball simulation where Dr. Ezrailson first shot the cannon at 90 degrees, and we saw that the cannon went straight up and came straight back down. Next, she shot the cannon at 75 degrees and the ball formed a parabola. Then she asked the class which degree would we point the cannon in order for the ball to shoot the longest distance. The answer was 45 degrees. Lastly, we made paper airplanes in order to see who could make one with the longest hang time. My paper airplane was not very successful(14 ft.), but I think with a little different folding technique and a stronger throw it could have flown longer and further.
