Purpose
Our task was to choose a sport that involves an object in motion, and find the physics behind that object. For our sport we chose archery. We calculated the force of the drawback, the velocity of the arrow and the potential/ kinetic energy of the string. Once we got all of our calculations, we were to make a video showing what we calculated and techniques on how to improve on the sport. You can see the video below
THE PHYSICS BEHIND ARCHERY VIDEO!
Key Points
Horizontal Velocity - the horizontal velocity of an object. In archery the horizontal velocity is the velocity of the without the downward motion.
Vertical Velocity - the vertical velocity of an object. the vertical velocity in archery is the velocity it takes for the arrow to fall.
Total Velocity - the hypotenuse of the vertical and horizontal velocity because the Pythagorean Theorem which allows you to find the velocity accounting for both the horizontal and vertical velocity. you can find the total velocity bey using a ² + b ² = c ² where A is the vertical velocity, B is the Horizontal Velocity, and C is the Total Velocity
Impulse - it is a certain amount of force applied over a specific amount of time. This is related to the release of the arrow.
Momentum - the amount of force behind an object, making it harder to stop due to Newton's first law, which states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
Vectors - a quantity with direction and force. This is used for the flightpathof the arrow.

Reflection
PeaksWe worked together nicely, we did not have any problems with dividing up the work evenly.
We were efficient in filming and narration. We improved on our calculations when we were informed they were either the wrong kind of calculations or incorrect. |
PitsWe had trouble finding a solid date to film, maybe we could have set a schedule for possible dates
At times we were a bit off task, after recording our results, we just fired the arrows. I was not flexible in time due to my many extra curricular activities (which ties into my first pit) I needed to be less irritable. I was stressed with other activities as well as the project. |
