Evidence of Work

For the second project we did in the STEM program at San Marin, we made videos about the physics of sports. In the group that we were assigned to, we had to choose a certain sport and make a video about a certain action in that sport. In the video we had to explain the correct way to perform the action and the physics involved in the action.

The group that I was assigned to was with Antonia Doyle, Stephen Newman, and Kaia Ring. We decided to do the action of throwing and catching a baseball for our video. We threw the baseball from third base to second base which is a distance of 90 feet and the baseball that we threw weighed about 0.145 kilograms.

Physics

Force Exerted/ Force Applied: the force that is exerted on an object by another person or object. The equation that is used to solve for force exerted is: f(force) times t(time)= m(mass) times v(velocity.) We used this equation to find the force that is exerted on the baseball from the throw.

Force of Impact: the force that occurs when one object meets another. The equation that is used to solve for force of impact is: f(force) times t(time)= m(mass) times v(velocity.) We used this equation to find the force of the baseball when it was hitting the glove.

Momentum: the tendency of moving objects to keep moving, or how hard it would be to stop. The equation that is used to solve for momentum is: p(momentum)= m(mass) times v(velocity.) We used this equation to find the momentum that was transferred to the baseball.

Horizontal Velocity: the rate of a distance covered in a horizontal direction. The equation that is used to solve for horizontal component of velocity is: v(velocity)= d(distance) divided by t(time.) The horizontal velocity was then used in other equations, for example the forces and momentum equations.

Vertical Velocity: the rate of a distance covered in a vertical distance. The equation that is used to solve for vertical component of velocity is: a(acceleration)= v(velocity) divided by t(time.)

Total Velocity: the actual velocity of an object. We used the Pythagorean Theorem to solve for the velocity of the ball, which is: a²+b²=c². We used the horizontal and vertical velocity components of the ball as the a and b of the equation to find the total velocity.

Calculations

Reflection

Throughout the project there were various things that my group and I could have improved on. The first example example is that we could have included more people in the actual video. My group was very good at collaborating throughout the project but we could have included people into more roles in the video. An example of something that I could have improved on was my time management. Although my group was working very well and was determined to finish task, I waited to the last minute to finish the editing of the video. Since I was the only person that was able to use iMovie, I was responsible for completing the editing of the video. Instead of spreading out the task of editing the video over a few days, I waited to the last day. Although the video was completed on time, I could have relieved some of the stress for myself and my group by managing my time better.

Even though there were some things we could have improved on, our group did a lot of things very well together. One example of something my group did well together was that we had a great work ethic through the entirety of the project. We were determined to get the project completed and to do very well. Our group was even one of the first groups to be finished with the whole project. Another example of something we did well was that we managed our time well. Since we were so determined to finish the project on time, our group was very efficient most of the time. For example, we split our tasks up so that we could finish multiple parts of the project at a time. Altogether our group worked very well together because of our work ethic and time management.
