Ticker Timer Experiment!
![Picture](/uploads/2/3/1/5/23159020/6494686.gif?209)
Aim: To analyse 2 drags-strips produced by a dynamics trolley moving with a constant speed.
You will need: 1x ticker timer, tape, 1x dynamics trolley, 400 grams of weights, 2x 2.0 meters of string.
Method:
1. Fix the pulley to the end of the bench top with the clamp supplied.
2. Attach once end of the string to the trolley and the other end to the weight hanger.
3. Attach about 2 meters of paper tape to the other end of the trolley with sticky tape. Thread it through the timer.
4. Connect the timer to the A.C. outlets of the power supply. Set the power supply to 12 volts.
5. Load the weight holder so that its total weight is 200 g.
6. Position the trolley so that the weight holder is 20 cm from the floor.
7. Start the timer!
8. Release the trolley so that it is accelerated by the 200 g. Allow the trolley to roll freely up to the pulley. Label this drag strip 1.
9. Repeat the steps 5 to 8, but this time use 400 g of weight. Label this drag strip 2.
10. Produce drag-strips for each member of your group.
11. Analyse your drag-strips!
