Unit 3 cont.


Today, we learned about Acceleration, and was introduced to the Galileo experiment. Although I had heard about his findings, it was still hard to understand why when we saw the demonstration. Mr. B dropped a tennis ball and volleyball from the same position in the air. To our amazement (no matter how many trials we conducted), the two balls, which are clearly different in weight, hit the floor simultaneously. This reminded me of the free fall ride at knots berry farms. Regardless of how many people in the carts, (how heavy the cart is) the cart still falls at the same rate. This shows that gravity affects all objects regardless of mass. Before this lesson I would have just assumed that carts with more people and therefore more weight would drop at a faster rate on the ride. Yet Galileo's findings continuously proves to us that even though no one was on the ride, the cart would still drop at the same rate as a cart full of people, because gravity affects all objects equally.
