What is the hypothesis of the ticker timer experiment?
Hypothesis: The ticker tape time will accurately represent the motion of electricity through. the hammer which will dot the paper to illustrate the motion of the electrons back and forth.
How do you analyze a ticker timer tape?
If we move very fast thence that the distance between the dot will be further the dots are far apart so the object move is higher speed okay move is higher speed. So that is how we analyze.
What is the purpose of a ticker tape experiment?
The ticker tape timer works by making dots on a paper tape at equal time intervals (approximately every 0.1s in this experiment). It is an excellent way for beginning physics students to experience the measurement of motion. Students will record and graph the motion of a car that moves with constant acceleration.
How do you calculate average acceleration of a ticker timer?
In order to find the acceleration. We need to determine the initial velocity the final velocity and the time taken for the velocity. Change the final velocity can be determined.
What is the frequency of the ticker timer?
50 Hz
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 .)
How do you find average velocity from ticker tape?

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 do I calculate average velocity?
Average velocity is calculated by dividing your displacement (a vector pointing from your initial position to your final position) by the total time; average speed is calculated by dividing the total distance you traveled by the total time.
What is difference between speed and velocity?
Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement. Put another way, speed is a scalar value, while velocity is a vector.
What is the uncertainty of ticker timer?
Experimental Uncertainties
All instruments have instrumental uncertainty. In this case the stopwatch has an uncertainty of 0.01 s and the ticker-tape timer may not be exactly 60 Hz.
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.
What is the frequency of a ticker 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 .)
What is frequency of ticker timer?
What is ticker tape diagram?
A dot diagram (sometimes called ticker tape diagrams or oil drop diagrams) represents the position of an object at constant intervals of time (like every second) with a dot. The pattern of dots reveals information about the nature of the motion.
What is the unit velocity?
Velocity is a vector expression of the displacement that an object or particle undergoes with respect to time . The standard unit of velocity magnitude (also known as speed ) is the meter per second (m/s). Alternatively, the centimeter per second (cm/s) can be used to express velocity magnitude.
Why is velocity zero?
When is Velocity Zero? The object has zero velocity when it does not displace with time. The velocity of the object is zero when there is no displacement of the object. The position of the object between two different time intervals remains the same.
Is speed can be zero?
The average speed cannot be zero unless the body is stationary over a given interval of time. Average speed is the ratio of the total distance travelled by a body to the total time interval taken to cover that particular distance. However, an average velocity can be zero.
What does the frequency of a ticker time mean?
If the ticker-tape timer has a frequency of 50 Hz, it means it punches 50 holes in 1 second. Hence the time interval to punch 1 hole is 1/50 = 0.02s.

Is ticker tape still used?
Paper ticker tape became obsolete in the 1960s, as television and computers were increasingly used to transmit financial information. The concept of the stock ticker lives on, however, in the scrolling electronic tickers seen on brokerage walls and on news and financial television channels.
What is unit of viscosity?
The unit of viscosity is newton-second per square metre, which is usually expressed as pascal-second in SI units.
What is the SI unit for time?
The second
The second, symbol s, is the SI unit of time. It is defined by taking the fixed numerical value of the cesium frequency ΔνCs, the unperturbed ground-state hyperfine transition frequency of the cesium 133 atom, to be 9 192 631 770 when expressed in the unit Hz, which is equal to s-1.
Is velocity is positive or negative?
Velocity: The velocity of an object is the change in position (displacement) over a time interval. Velocity includes both speed and direction, thus velocity can be either positive or negative while speed can only be positive. Another way to say this is that speed is the absolute value of velocity.
What are the three types of velocity?
The different types of velocities are uniform velocity, variable velocity, average velocity and instantaneous velocity.
