Physics Concepts From Our Project

• Mass of Projectile (how heavy our projectile is) - 10 grams

• Horizontal Distance (how far away the projectile went)- 43 meters

• Time in Air - 1.79 seconds

• Vertical Distance (how high it goes) - 3.9 meters

• Horizontal Velocity (how fast the projectile goes horizontally) - 24 meters/second

• Vertical Velocity (how fast the projectile goes vertically) - 8.78 meters/second

• Total Velocity (the combined velocity of the projectile) - 25.5 meters/second

• Angle of release (where the arm lets go of the ball) - 55 degrees

• Initial Spring Potential Energy (how much energy in the spring) - 19.6 Joules

• Kinetic Energy of the ball (how much energy the ball has while in motion) - 3.924 Joules

• Percent of energy Converted (how much energy is converted to the projectile) - 165%

Reflection

Over the course of this project my team and I worked well together to come out with a well working catapult. We knew how to communicate, and when things went wrong we pivoted quickly. Our first attempt at the catapult was good, but when we tested it out we found that the wood was to weak to support the power, and it ended up breaking. So we quickly pivoted as a team to come out with a much sturdier and well working catapult in the end. We also worked well when implementing the eight modifications to the project, we got it doing well and quickly. I was the one who did most of the work actually constructing and designing the catapult,, while my team mates tested and made sure we had everything we needed.

Some things we could of done better as a team was dividing the work more evenly. I found that I was building most of the project. I also want to stay on task more when we are in the makers space, because it is easy to get distracted with everyone else and their projects, instead of working on your own.
