The ticker tape can be used to study
The tape is usually attached to, and pulled by, a moving trolley.
The analysis of the tape enables one to better understand the motion
of the trolley. From the frequency of the ticker tape, one can get
From the lengths between the dots, the distance travelled by the
trolley in the knowntimecan be measured. Using
the two quantities (distance andtime), velocity
can be calculated - and from it. acceleration
can be derived.
For example, in the example above, with a frequency of 50Hz, thetimebetween
1/50Hz = 0.02s
