Everyone knows the blue, padded gym walls. If someone was to offer you 10 dollars to punch one as hard as you could, there are at least 5 of you out there who would take it. Well, had i known the physics of a punch, I wouldn't have ended up with a broken pinky. If you're going to punch a blue wall in the gym, keep this in mind. The longer the punch connects with the wall, the smaller the force was. This makes sense logically,, if i hit something hard my hand will bounce back from the collision.
Sound waves can be seen on an instrument called an Oscilloscope. The idea behind sound waves is that noise emits tine waves that we pick up on. the distance between each wave (called a crest) is wavelength. frequency is the number of waves that pass a point each second. Amplitude is the measure of energy in a sound wave. Sound waves are more easily graphed through trig, as sine and cosine produce graphs in these waves. The higher the intensity of the sound, the bigger the wave is. Sound, like li
This can simply be explained with kinematics. We can apply a free-fall vertical table here, because without the blog posts being accepted this quarter, my grade will be in free fall. Gravity is always accelerating downward at 9.81 m/s^2. Distance, (Distance from my bed the computer) LOOKS like 2,712,268,800 meters (its 3 meters, but were using my perception, Okay?) my initial velocity is 0 m/s, i'm starting at rest, laying down. I know i can move really fast, and there's no distance that can get
Procrastination. Really, it's responsible for so much (or so little?). Turns out, It is easily explained by physics! Newton himself theorized that AN OBJECT AT REST WILL STAY AT REST UNTIL ACTED UPON BY AN OUTSIDE FORCE. Turns out I'm not lazy! When I lay in bed while I know i could be productive, It's not my fault. Physics says that I won't move until an outside force makes me. Typically this force is my parents after viewing the infinite campus portal.
As sit at my desk, distractions seem
Today in class we covered more laws of motion. As it turns out, the action of walking/jumping/running (Really, pick one) aren't only because you push down and forward. The floor is actually PUSHING RIGHT BACK. "Equal and opposite reaction", one can almost hear Mr.Meredith mumble. But in stricter terms, every force is met by and equal and opposite force, which is Newtons Third law. When one pushes off the floor, they find themselves back on the floor soon after (at least, one would hope). This re
