Unformatted text preview: ▪ Average velocity ▪ Instantaneous velocity Acceleration ▪ Constant acceleration ▪ Average acceleration ▪ Instantaneous acceleration For each quantity: Name of quantity: ( this is the quantity measured) Procedure: ( How did you measure this. A diagram is valuable) Calculations :(any needed to find that quantity.) Something creative….A drawing, a diagram, a question, a sentence that represents your thinking from this class period. I own: I don’t understand: What is the instantaneous acceleration of a pen that I toss in the air: Right after I release it When it is at the top of it’s flight Just before I catch it...
