Finally! After months of waiting, I’ve finally put together another PwP video. Check out the video below for a few simple demonstrations of Newton’s laws of motion in the Puzzle Maker.
Hey Nathan! Don’t forget, you owe me a blog post. Tell us about your class!
How I determined that propulsion gel accelerates you to 12 m/s2:
First, I measured the time it took to reach top speed on propulsion gel.
Breaking the video down frame-by-frame, you see that you reach a top speed of 800 u/s in ~1.3s. Remembering that acceleration = (change in velocity) / time lets us calculate acceleration in game units. Then, I convert game units to meters by using 128 u = 1 panel and 1 panel = 2.4 m (described in depth here) to find that the acceleration due to propulsion gel is 12 m/s2.
