What information can you determine using a ticker timer?
It is a device to record an object’s movement by taking a spot on a paper tape at regular time intervals. A typical ticker timer is plugged into a household outlet. So the ticker cycle of the ticker timer is closely related to the frequency of the supplied household power.
What is the time interval for 10 ticks on the ticker tape?
0.2s.
Ticker-tape charts There are 10 ticks on each length. This means that each length represents a time interval of 0.2s. Ticker-tape charts are very useful in analyzing the motion of an object.
How would you describe the motion of ticker tape?
A stationary “ticker” makes a mark at regular time intervals. A moving object drags a tape past the ticker, and a trail of marks is left on the tape. For an object moving with uniform velocity the marks are spaced uniformly on the tape….Motion with constant velocity.
| Time (t) | Position (x) |
|---|---|
| 1 s | 2 m |
| 2 s | 4 m |
| 3 s | 6 m |
| 4 s | 8 m |
What is the relationship between the length of the ticker tape and time?
Ticker Tape – Example 1 There are 10 ticks on each length. This means that each length represents a time interval of 0.2s. Ticker-tape charts are very useful in analyzing the motion of an object.
What is the time between any 2 dots on a ticker tape?
The ticker timer prints a dot 50 times per second, so the time between each dot is a fiftieth of a second, or 0.02 seconds.
What types of voltage supply are used for the ticker time?
Operates at a frequency of 50 to 60Hz, equivalent to that of the mains power supply, and is supplied with one roll of ticker tape and a pack of 100 Carbon Discs. It will give good results if operated from a 6-12V AC power supply.
How are ticker timers used to calculate acceleration?
Ticker timers and tape create representations of motion in a straight line. A strip of tape is attached to a moving object, such as your hand, and passed through the timer. The timer marks the tape with a dot at regular time intervals. Different speeds result in different distances between the dots.
What can be observed from the ticker tape?
The distance between two adjacent dots on a ticker-tape represents the displacement of the object in a tick (0.02 s). If the object moves quickly, the dots are far apart. If the object moves slowly, the dots are close to each other.
How are ticker timers used to measure speed and acceleration?
A ticker timer is a device used to record the motion of an object. It works by making marks upon a piece of tape at regular time intervals, which is in turn attached to a moving object. The spacing between the marks allows for the calculation of both velocity and acceleration.
What does it tell you if the dots on a piece of ticker tape?
The close together dots represent a slow-moving object because it didn’t travel far between each tick. The far apart dots represent a faster-moving object. And that also means that dots getting further apart represents an object speeding up. And dots getting closer together represents an object slowing down.
How many dots does a ticker timer do?
50 dots
Most ticker-timers vibrate at 50 Hz, and thus make 50 dots per second.
What is the frequency of a ticker tape timer?
Most ticker-timers vibrate at 50 Hz, and thus make 50 dots per second. For these, the expected mean value of one tick is 1/50 second, or 0.02 s . (Some ticker-timers will give dot-making frequency of 100 Hz, and for these the value of one tick is equivalent to 1/100 seconds or 0.01 s .)
Why do we use alternating current in ticker tape?
The Physics of the ticker timer A voltage of 12 Volts AC (alternating current) at a frequency of 50Hz powers the ticker timer. This alternating voltage causes the vibrating arm to be attracted by and released from the electromagnet at a rate of 50 times a second.
Where are ticker timers used?
A ticker timer is a simple device that can be used in measuring time and displacement when analyzing the motion of an object. The measured time and displacement can in turn be used in determining the velocity. The key property of this device is that it makes a mark at a frequency of 50 dots per second.
When the ticker tape dots are having greater distance between them the object?
A large distance between dots indicates that the object was moving fast during that time interval. A small distance between dots means the object was moving slow during that time interval.
How do I find the velocity of a ticker timer tape?
The velocity of a section of ticker timer tape can be found by knowing the time and displacement and applying the formula: E.g.: Velocity using interval 1: Velocity using interval 2:
What is a ticker timer?
A ticker timer is a piece of equipment that can be used to measure both time and displacement. From these measurements it is possible to calculate velocity and acceleration. A ticker timer makes a mark every 0.02 seconds.
What was the problem with the ticker tape timer?
Equipment Error: During the experiment, there were difficulties that sometimes occurred with the ticker tape timer. Though the machine worked quite effectively the problem was encountered with the purple carbon disc that created imprints on the ticker tape paper.
What improvements can be made to the ticker tape experiment?
There are two major improvements that can be proposed to make the data collected from this experiment more precise and accurate. The first improvement would be the creation of a tool to allow one person to operate both the ticker tape timer and the release of the car.
