Hypothesis-
Quinn- I think that the golf ball will go the farthest due to the areodynamics but we need to include the weight. Maybe the pen or pencil will get the farthest because if it flies right it will be the perfect thing to launch due to its areodynamics like the golf ball but the pen and pencil both are light. If there is weather we will need to include that also.
Nate- I think the pencil will have the most velocity due to its great aerodynamics. The shape of the pencil helps a lot with its aerodynamics with the point to break through the air and a slim design that also helps it cut through the air with the most velocity.
Rodney- I think the golf ball will have the most velocity because of its aerodynamics. The indentations on the ball will cause it to use the air to flow around it.
Experiment-
Materials-
1. Material Launcher
2. Pen
3. Pencil
4. Rubber Frog
5. Tack
6. Golf Ball
7. Open Space
8. Yard stick
Procedures-
(1) Make the material launcher from scratch. (2) Gather all materials. (3) Find open area to launch materials. (4) Do a test with each of the five things to launch. Do three tests with each. (5) Record information.
Variables-
CV- launcher, rubber band pulled back, how we measure
IV- The item
DV- distance, wind, weather,
Control-how we made the launch, the items we launched
Observation-
Conclusion-
Nate- This experiment was focused on velocity so we launched object off of a launcher we built the only problem was velocity involves timing the objects before they hit the ground, which is something we didn’t do. My hypothesis was not supported by this experiment because the pencil didn’t make it as far as the pen because of its higher mass. I talk about the mass because in this experiment we couldn’t calculate the velocity because we need the timing but we did measure the distance of the objects. Even though there was different velocities between each object so our results came down to Newton’s second law Force = Mass x Acceleration. If the mass goes down the acceleration or distance goes up which explains why the pen went so far, that equation can go the other way too.Take the golf ball for example because of its large mass the acceleration went down, so it did the worst. Other factors included wind resistance and drag. The pen was great in this category too,. Due to its design it had the least amount of drag and the least air resistance. The tack had the least amount of mass which means it had the most acceleration but was stopped by wind resistance and drag due to its flat design in the front.
The experiment was somewhat of a success although there were a few flaws. First we didn’t time the launches like I said. Second we had started this 1st semester and didn’t pick it up for a while. Finally we didn’t get that deep into the research which explains why we didn’t time it.
