Velocity of a motion can be determined by using ticker tape through the following equation:
Caution!:
t is time taken from the first dot to the last dot of the distance measured.
Example:
Diagram above shows a strip of ticker tape that was pulled through a ticker tape timer that vibrated at 50 times a second. What is the
a. time taken from the first dot to the last dot?
b. average velocity of the object that is represented by the ticker tape?
Answer:
a. There are 15 ticks from the first dot to the last dot, hence
Time taken = 15 × 0.02s = 0.3s
b. Distance travelled = 15cm
