Unit 2

In this video I walked back and forth across my living room. I started by my back table (starting position) and returned to the same spot after. Walking is a type of motion and since I started off resting, I accelerated twice: once when I started walking, then when I stopped after finishing my course. Acceleration is to start, stop, go faster, or go slower, so basically a change in speed or velocity. When I was walking, I accelerated forward to move, but then accelerated backwards in order to stop myself. The distance was about 4 meters total, 2 meters each way, but my displacement was 0m. Why? Because I ended up returning to the spot I started at! Distance is the total path length, and displacement is distance with direction.
