Hi there this is my physicis assignment please help me get a A+
A ticker-timer is a device which can be used for recording both time and distance. A ticker-timer vibrates up and down every 1/50 second. The important fact about ticker-tapes is that the time between dots is always the same. Most ticker-timers work on alternating current, i.e. at 50 cycles per second; this is why there is 1/50th of a second between dots, or each dot will be made 1/50th of a second apart.
If set up correctly, the ticker-timer will leave a dark mark on a piece of ticker-tape. If this tape is attached to a moving object, a series of dots appear on the ticker-tape as it is pulled through the ticker-timer. The further apart the dots appear, the faster the object is travelling. The closer the dots, the slower the object. If the dots are equally spaced as on Tape 1 below, then the object has constant speed.
You need to write a very detailed general introduction atleast 200 words
Aim:
Hypothesis;
Apparatus: Needs to include a diagram A ticker-timer.
ticker timer | |
ticker tape | |
power pack supply and | |
connecting wires | |
pencil, ruler, scissors and glue |
Method:
Result; I have attached the table which you need to fill in
Time (seconds) | Distance (m) between dots | Speed = distance / 0.02 | Acceleration = (speed2 - speed1) / 0.02 |
0.02 | |||
0.04 | |||
0.06 | |||
0.08 | |||
0.1 | |||
0.12 | |||
0.14 | |||
0.16 | |||
0.18 | |||
And so on; if needed |
Result qualitative and quantitative (220 words at least)
Find average acceleration:
Include atleast 3 graph to back your results
Discussion (maximum 600 words): Should include: 1. what happened (outline findings and what they mean. Eg how does result compare to what was expected) 2. what went wrong (errors) 3 what could be improved (eg different equipment etc). Write in pin point detail
Conclusion: Was your hypothesis supported or not?
