If a long ticker tape is used, a large number of dots can be recorded on the ticker tape. As
such, the ticker tape can be divided into strips with an equal number of ticks. These strips are
cut and attached side by side on a piece of graph paper to form a ticker tape chart as shown in
Figure 2.14.

Other than ticker timer, photogate system and electronic timer can be used to study
linear motion more accurately. Figure 2.15 shows a photogate system and an electronic timer
used with a non-motorised trolley moving on an inclined aluminium runway.
