Physics
For this experiment, I and my partner decided to find out how different mass can alternate the average speed of the parachute. We did this by changing the mass of each parachute and dropping it at a certain height. Our Independent variable is the mass and our dependent variable is the time and speed of the parachute. Our controlled variable is everything else, like the humidity, the wind speed, the degree, the distance, the length of string, the place we drop the parachute etc.
Hypothesis: Our hypothesis is that, the heavier the parachute the faster the speed/ terminal velocity
Our method:
- First we collected all our equipment’s. This includes: 5 zip lock bags, a long piece of string, 5 plastic bags of the same size and scissors.
- We add sand to 5 zip lock bags, to a certain mass. For example: 5g, 30g, 15g etc. and we left one empty
- Then we cut the long piece of string into 5 equal parts, using a ruler to measure
- After that we made a hole in each zip lock bag with a scissor, this is for the string to get through the zip lock bag.
- After that we put the string through the hole of each zip lock bag and through the holes of the plastic bag , and securing it with a knot
- We then went to the second floor and one of us went down to the first floor to time
- The person on the 2nd floor then dropped the parachute in the count of three and the timer will start timing it.
- We did step 7 twice for each parachute, to make the results more accurate.
