A Ticker Timer is a constructed scientific device that measures the velocity of a moving object. Tape is attached from the ticker timer to the object of choice. Drops of ink are applied to the piece of paper once the object starts of move. If the moving object accelerates, the distance between dots will increase; if the moving object decelerates, the distance between the dots on the ticker timer will decrease. A ticker timer has a small hammer that marks a tape pulled through it. The hammer puts 50 dots on the tape every second (5 dots in a tenth of a second). By attaching the tape to an object with movement, we have a record of that movement which shows the distance traveled every part of a second.
