SWINGING A BAT


so i have this poster of derek jeter in my room cause hes my favorite baseball player :) and he's swinging the bat which is something related to physics. as you can see in the poster he is kinda twisting his body and following through with his swing. in baseball when the ball approaches the batter, he steps into the pitch and twists his body to transfer energy into the bat which causes the ball to go far!

DANCE SHOWCASE LIGHTS

On friday i went with some friends to watch dance showcase. To set the scene there were many spotlights shining on the stage in Lower Gym. I realized that there are physics involved with these lights and because they had filters over the white light source the spotlights were emitting colored light. According to doc! the filters on the lights are a little more fancy then just simple little plastic.

GLASSES


i am nearsighted, which means my eyes are unable to focus on things far away. for my glasses, i have diverging lens so they are thinner in the center and thicker on the outside. the rays of light enter through the lens travelling parallel to its principle axes but diverge after passing through. in a converging lens which is thickest in the middle, the rays of light intersect after entering the lens.

POOL TABLE

After prom i stayed at my friends house and while i was there i watched as my friends played pool on his pool table and i realized this is a perfect thing for my physics blogs because it involves Change in KE and Change in Momentum. It also shows newton's first law of motion because the colored balls are at rest when the cueball strikes it and then the colored ball moves. Also according to Marcus the balls slow down due to friction with the table
