Description
During these past few weeks, the students involved in STEM worked on videos breaking down the physics of many different types of sports. The goal? To help athletes better understand how to excel at their sport. My group made a video describing the physics of shooting an arrow. The video covers drawing the bow, firing the arrow, the arrow's flight, and hitting the target. To make the video, we started out by writing the script and storyboard. After that, we filmed shooting the arrow for a few days. Next, we filmed the introductions. Finally, we filmed each group member talking about each individual step involved in the shot. After some editing, the above video was the result. This project was both fun and challenging, and was a good overall experience for everyone.
Reflection
During this project, I enjoyed working with new people and getting to know them. I also liked working outside and hands on with a bow and arrow. One thing I did well was to help contribute my ideas. For example, when we were filming the shot, I suggested using different angles. Another thing I did well was help with the group's time management. An example of this is when I said we should film the archery shots first and the physics segments later. While filming, it was challenging to get the right angle during the bow shot. Another difficult part was being organized when bringing and using supplies. Two things I can improve upon next time are organizing supplies and using better angles when filming.
Concepts
Velocity- Velocity is how far an object travels in a given amount of time. It is calculated by dividing distance and time. When the arrow is flying through the air, it has a certain velocity.
Acceleration- Acceleration is the rate of change in an object's motion. It is calculated by dividing the change in velocity over the change in time. When the drawstring is released, the arrow accelerates.
Projectile Motion- There are two components to projectile motion: horizontal and vertical velocity. Horizontal velocity is calculated by dividing distance and time. This remains the same during a parabolic arc. Vertical velocity is calculated using the acceleration of gravity and changes throughout the arc. Vertical and horizontal velocity do not effect each other. However, when the arrow travels through the air, it has mostly horizontal velocity because the arc is almost nonexistent.
Impulse- Impulse is how much force there is in a collision between two objects. It is calculated by multiplying mass and velocity and then dividing those by time. When the arrow hit the target, there is a certain impulse.
Momentum- Momentum is how much energy an object carries with it. It is calculated by multiplying mass and velocity. As the arrow moves through the air, it has momentum.
Kinetic Energy- Kinetic energy is how much energy an object has due to motion. It is calculated by multiplying 1/2 mass and velocity squared. The arrow has kinetic energy while flying towards the target.
Potential energy- Potential energy is the energy of an object in a certain position. In this case, the arrow has spring potential energy, as opposed to gravitational potential energy. potential and kinetic energy are equal.
