Sticky Collisions

Today my brother and I were playing football in our backyard. While I was getting tackled I realized that physics was taking place as I was thrown to the ground. What had occured during the tackle was a sticky collison. Before the tackle my brother and I had seperated masses and velocities of our own. But as he tackled me we had a combined mass and a final velocity. Luckily my mom was able to capture this beautiful physics taking place at our very home. I glad it did not rain today.

Potential & Kinetic Energy

While I was up on my wall trimming the trees I took a moment to step back and think about the physics that were taking place right in front of my eyes. As I stood there I realized that I had a certain amount of potential energy with relation to the ground below me but no kinetic energy. When I jumped off the wall and onto the ground I observed that my potential energy decreased as my kinetic energy increased. I also noticed that while both my potential and kinetic energies were changing, my total energy remained constant throughout the jump. What a beautiful day.
