Copy the problem below into a text editor or word processor.
This form accepts only text so a text editor such as Notepad is fine.
You might prefer for your own reasons to use a word processor (for example the formatting features might help you organize your answer and explanations), but note that formatting will be lost when you submit your work through the form.
If you use a word processor avoid using special characters or symbols, which would require more of your time to create and will not be represented correctly by the form.
As you will see within the first few assignments, there is an easily-learned keyboard-based shorthand that doesn't look quite as pretty as word-processor symbols, but which gets the job done much more efficiently.
You should enter your answers using the text editor or word processor. You will then copy-and-paste it into the box below, and submit.

The problem:
Answer the following:
How accurately do you think you can measure the time between two events using the TIMER program?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line): First I want to state that no human is going to be dead on accurate when it comes to a timer because the time it takes for the brain to realize that it needs to make a movement will take at least a sec to get the nerve impulse from the brain to the muscle to respond and the same again if on point to stop the action.

What is the shortest time interval you think you would be able to measure with reasonable accuracy?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
To be reasonably accurate im thinking it will need to be at least two sec to which would be normally how long it takes the brain to respond to send and receive a message for the average person to start and stop the timer.

How does the percent error in timing intervals change as the time between the events gets smaller?
answer/question/discussion: ->->->->->->->->->->->-> (start in the next line):
As the time intervals gets smaller the quicker and better reaction time one need to make an accurate assessment. Again it goes back to the definition of reaction time, its the time it takes for a person to realize they need to move.

How accurately are you able to measure the positions of the ball and the pendulum in the initial video?
