Free fall session 3: CORAL

Today we have had class with Mr. Canning (as our teacher wasn't here). I continued with my experiment and I have finished it. I have changed a bit the way I was doing it although the variable is still the mass of the ball. However, now I have 5 new different balls with different masses and I did each of them 5 times. 

For next class, I will record the experiment as I didn't do that during this class. I threw the ball from a distance of 50 cms from the container and I used gel to calculate the depth of the ball.

BALLS:

Ball 1: 5 grams

Ball 2: 15 grams

Ball 3: 30 grams

Ball 4: 50 grams

Ball 5: 80 grams

RESULTS:

Mass of the ball (grams)    Depth of the ball in the gel     Average of the depth
