Motion Diagrams are qualitative representationd relative size and directions of velocity and acceleration at rest V=0 the direction that the velocity arrow points is the direction the size of the arrow is th qualitative is the speed acceleration has to be to the right when increasing speed velocity and acceleration point in the same direction when decreasing velocity and direction point in opposite directions (inversely related)

Ojective: What is acceleration due to gravity ? Hypothesis: 9.8 m/s Procedure: I used spark tape the height of the celiing to the floor. i distinguished the begginning of the tape from the rest. Once the spark tape was put through the spark timer I taped a 200 gram weight to the spark tape. Once the spark time was turned on and set to 60 hertz i dropped the weight from the ceiling. I counted 20 dots indicated by the spark timer and calculated the time to make my graph.
