Ice Water

Today my whole family went down to my grandma's house for dinner. We had lots of delicious food like steak, noodles, and stew. While eating dinner, I had drank all my water and went to get a refill. While adding ice to my cup of water, I noticed that the water level was rising with each ice cube I added to my cup. Then I realized it was like the displacement we had learned about in Physics. The ice caused the water to change position positively. It was water displacement! Adding ice caused a positive displacement, while removing ice caused a negative displacement.

In addition, I noticed that by dropping the ice cubes into my cup, the cubes were falling from 0 m/s with a -9.8 m/s/s acceleration. However, because each added cube raised the water level, the distance each subsequent cube had to fall became shorter than the previous cube. As a result, the last cube I added fell a shorter distance in less time with a smaller final velocity than the first cube I added.
