So im writing a physics lab. Here's part of the rubric. "Fully explains physics concept constant acceleration including a definition, an example from your video (stop motion video we had to make), the cause, and a FBD" My question is what is the cause of constant acceleration? Our example in the video is a risk piece moving across the board moving a couple cm across every picture. Would the cause be displacement and velocity or something? Oh yeah, title is suppose to be constant*.
