Ticket Timer concepts; memorise Flashcards
What is a ticker timer? What does a ticker timer tell you?
A ticket timer is a device that record’s an object’s movement by printing a dot at regular time intervals. A ticket timer tells you the speed or the velocity of an object.
What are the objects needed for a ticket timer?
A ticket timer needs graph paper to put inside the ticket timer.
It also needs a power supply, possibly wires and a ticket timer :/
What is the method of starting a ticket timer? (The very basics)
Connect the ticket timer to the AC terminals (bottom 2 parts) of the power supply. Use 6 TO 8 VOLTS and turn the ticket timer
Test the noise first before use
Cut a considerable amount of graph paper and slide it inside the ticket timer
Depending on the situation, slide it out at a constant speed, accelerating or decelerating
Analyse the strip
If the dots are close together, then what does it show?
Close dots show how the paper was slided out at a SLOW SPEED
If the dots are far apart, what does this mean?
Far apart dots mean the graph paper was slided out at a HIGH SPEED
If the dots are all equidistant from each other, what does this tell you?
It was pulled out at a constant speed
If the distance between dots had increased, was it acceleration or deceleration?
An increasing distance between dots mean ACCELERATION
If the distance between dots had decreased, what does this tell you about the speed/velocity?
If the distance decreased, it means DECELERATION or NEGATIVE ACCELERATION
Always take note of which direction the paper was pulled out of
yes I WILL
How do you find the distance between the dots?
Using the velocity formula where velocity = displacement / time, IDK EDIT THIS ONE LATER
Why is the direction in which you started to use the ticket timer important?
It is very important since you need it for your analysis. If you slid the paper from the right, then at the end, the very right side of the paper would have been the graph paper’s starting point and the left side would be the ending point. The opposite would have occurred if it was slipped from the left side instead.

of how to find the velocity, distance between the dots and the acceleration of a ticket tape
ok
How often are dots placed on the strip of ticket tape paper? What is the speed in between the dots?
Dots are placed on the paper every 50TH OF A SECOND. THEREFORE, 0.02 OF A SECOND
