Question

I need some help to answer my lab questions:

1- Why is it necessary to cock the launcher the same every time?

2- How would your photo-gate measurments have been affected if you had st the photo-gate beam above or below the center of the ball?

3- How would your measurments have been affected if you had done this on the moon outdoors?

4- How would your measurments have been affected if you didn't have the photo-gate close to the mouth of the launcher?

5- Which of the two methods used to find the muzzle speed do you think is the most accurate? Explain why you think so.

you need to provide a lab description itself, not only questions
