While the concept of ticker tape timing has been widely accepted, traditional problems (the lack of calibration and the need to use special paper) often made this a difficult method to use.
PASCO eliminated these problems with a unique design which means that ticker tape timing is no longer a troublesome timing method.
Replacement Tape Timer Supplies (ME-9284) are available
Provides students with a visual demonstration of speed and acceleration. A moving object pulls a paper tape through the timer. The timer prints dots on the tape at equal time intervals. The result is a series of dots on the paper tape, representing the position of the object as a function of time.
From the dots on the tape, the distance traveled can be measured, and the average speed for each time interval can be calculated. Plotting position versus time enables one to determine the average speed. Plotting the average speed for each time interval versus time enables one to determine acceleration.
The paper tape can be attached to air track carts, dynamics carts, falling masses or other objects.
