A ticker tape timer is a device that makes a point on the ticker tape every time a whole wave of an alternating current passes through it the frequency used in the experiment. Experiment a: to show that a f set up the apparatus as in the diagram (the ticker tape timer is a device that puts 50 dots per second onto a long narrow piece of paper that passes over a marking device (rather like a pencil moving up and down 50 times a second). Can you prove newton's second law from this experiment page 1 of 2 1 2 next jan 5, 2012 #1 titaniumpen the trolley pulls along a tape as it moves, and the tape has to go through a ticker timer, which automatically dots the tape every 02 second the set up looks like this. 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.
If the ticker-tape timer produced 50 dots per second, find the acceleration of the toy car answer : 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 ticker-tape in figure above was produced by a toy car moving down a tilted runway if the ticker-tape timer produced 50 dots per second, find the acceleration of the toy car -1250 ms-2. A guide to motion in one dimension teaching approach in this series we continue on from the series on vectors and scalars by investigating the a simple ticker timer experiment is demonstrated learners are shown important units and how to convert between units.
The ticker-timer provides a simple means of collecting distance versus time data in motion experiments today it has been superseded by the data logger it is, however, worthwhile to have a familiarity with data collection using the ticker-timer. The relationship we can see through this experiment showed that as the mass of the object became greater, while the net force stayed the same, the acceleration became less when the mass and acceleration are graphed (on the graph titles mass and acceleration ) it doesn’t form a straight line, thus not proving newton’s second law. Attach the ticker timer to the ac power supply tape a 1m-long ticker tape to the trolley turn on the power so that the ticker timer is vibrating elevate one end of the bench and allow the trolley to accelerate down hill. I did the ticker tape experiment made a ramp, attached ticker tape to the end of a cart, thread the tape through the ticker timer, let the cart roll down the ramp ^^'' my question lets say my ramp had an imperfection, like a bumb or groove.
If the ticker-timer produces 50 dots per second, then a tick is equal to 1/50 or 002 seconds 4 step h of the procedure: the length of each tape is the number of centimetres that the trolley travelled in a fifth of a second, or 02 seconds. The ticker tape timer works by making dots on a paper tape at equal time intervals (approximately every 01s in this experiment) it is an excellent way for beginning. Ticker timers ticker timer experiment interpreting ticker timer tapes ticker timers consists of a small electric arm with a pin or hammer on it's end.
Apparatus needed: runway, two trolleys with velcro attached, power supply, ticker timer, ticker tape, balance, and ruler precautions: raise one end of the runway to negate friction and ensure the trolleys travel at a constant velocity. Ticker tape timer lab: changing velocity the experiment 1 take ~15 meters of ticker tape and tape it to the rear of your cart 2 put a disc of carbon paper on the pin in the timer (reuse them as much as you can) the carbon paper must be ink side up 3 feed the ticker tape through the staples and over the carbon paper 4 start the timer.
A thread a short length of ticker-tape through the ticker-timerif there is a carbon paper disc, make sure the tape goes underneath the disc b turn the ticker-timer on for a few secondsit vibrates rapidly and hits the top of the carbon paper it makes a lot of dots on the tape, at regular intervals. Experiment 1 this experiment is to measure the distance traveled and the speed of a piece of ticker tape using a ticker timer you will need: a ticker timer, a 12v ac. Investigation #2: acceleration due to gravity introduction the relationship between acceleration (a), speed (v), and time (t), for an object.
