Marble+Launcher

__**Goal:**__

 * We realize that all objects launched at the same angle with the same initial velocity shouold land in the same spot at the same time theoretically, but because of air resistance the distance a projectile travels and its hangtime are different depending on the mass. So our goal is to see how different massed balls land differently and the difference between their hangtimes to see just how much mass effects projectiles.

__**Procedure:**__

 * Get equipment(different mass marbles, launcher, tape, meter stick).
 * Find mass of marbles (6 different marbles).
 * Push the launcher to the farest click
 * Use meter sticks to measure the distance.
 * Shoot each marble to see how far it goes, shoot the marbles at a 45 degree angle.
 * Then calculate the speed of each marble

**__Data:__**

 * Marbles: #1: 2g, #2: 3g, #3: 4g, #4: 8g, #5: 16g.
 * Distances of marbles:
 * 1- 5.26 meters 1.4 seconds in air
 * 2- 4.85 meters 1.4 seconds in the air
 * 3- 4.72 meters 1.42 seconds in air
 * 4- 4 meters 1.39 seconds in air
 * 5- 3.55 meters 1.4 seconds in air

**__Data Analysis:__**
5.26=0+0+1/2*-9.8*T T=1.07347 seconds 4.85= 0+0+1/2*-9.8*T T=0.989796 seconds 4.72=0+0+1/2*-9.8T T=0.963265 seconds > 4=0+0+1/2*-9.8T T=0.816327 seconds 3.85=0+0+1/2*-9.8T T=0.785714 seconds
 * Marble 1: D=5.26 meters T=1.4 seconds without air resistance T=1.07347 seconds
 * Marble 2: D= 4.85 meters T= 1.4 seconds without air resistance T= 0.989796 seconds
 * Matble 3: D= 4.72 meters T=1.42 seconds without air resistance T=0.963265 seconds
 * Marble 4: D=4 meters T= 1.39 seconds without air resistance T=0.816327 seconds
 * Marble 5: D=3.85 meters T= 1.4 seconds without air resistance T=0.785714 seconds

== = = = = = = = = =__**Conclusion:**__= The mass of the marbles that we launched did not affect the time that they were in the air, which matches what should theoreticly happen, it does however affect the distance that the marble traveled in the air before it hit the ground. We found that the more massive the marble was, the less distance it traveled before it hit the ground. To prove this you can look at our data which show. how as we launched a larger massed marble its went less distance and how the time was basicaly the same each time, then for a visual representation of this same exact data you can look at our graphs. Our reasoning for why this may be is that the more massive a marble is the more surface area it would have which would cause more drag from air resistance and the more massive the heavier it would likely be so there would be more pressure pushing it down. Our reasoning for why the time remains basicaly the same is that since the marble moves slower each time which would make it take more time, but also travels less distance each time which would make it take less time, the two factors even out the time.
