Day: 8

Today, we continued our learning on motion but this time, we added motion going in two directions when earlier, we were only dealing with one. This made things a little trickier but after some practice, we got the hang of it. Something that was pretty surprising and interesting to me was the simple demonstration with the pens. Two pens were held above the ground at the same distance but one of the pens were tossed straight forward (no arc so the height didn't go any higher) while the other was dropped. Before this was demonstrated, we were asked what we thought would happen and many of us predicted that the one being tossed forward would land after (meaning that the one dropped would land first). We soon learned that in fact we were wrong and that both pens landed at the same time. This is because both axes are independent so the time doesn't differ between the two. This reminded me of a jump that my friends and I did off of some rocks and that of course when we jump, we are going a little higher but if one of us stepped off and the other (somehow) jumped only forward/horizontally, then both people would land at the same time!

  1. I like how you compared it to jumping into the water. It was helpful that you kept it short and were to the point.
