distance vs displacement



This weekend my whole family from my dad's side went to Maui. It was my Aunty Renee's birthday so the our parents planned to go and celebrate it on another island. It was really fun because all of my cousins were there and there were four pools with slides, caves, pool-vollyball and pool-basketball. We left on Friday after school and came back on Sunday. I noticed that there was physics in our trip that shows the difference between distance and displacement. Distance just measures the amount traveled. Displacement measures the amount traveled and in what direction. Displacement is the net change in position. The total distance and displacement that our family flew on the plane were different. The distance from Oahu to Maui is around 116.47 miles. So the total distance that we traveled on the airplane was around 232.94 miles, which is to and from Maui. But our displacement was zero. Even though we traveled 116.47 miles in one direction, we traveled that same distance in the opposite direction, making our total displacement zero. Our trip to Maui showed the difference between distance and displacement and how they measue different things.
