This past weekend it rained alot and i just began driving again. Because of my injury, i couldnt drive. Anyway, as i was driving to the soccer boys states, i got stuck in a lot of traffic because people were speeding and got into a multicar accident. This reminded me of what i learned in physics that if an object pushes another, the other object is pushing against it. The force is the same but the mass of one object may be larger and therefore the forces never cancel each other out. Throughout the whole weekend, I witnessed 3 car accidents. This isn't a good thing when i just started drving again, but i was aware of my surrounding and my SPEED limit because i know if i speed i could be in one of these accidents! I don't have a picture of one of these accidents but here's the cool soccer pics i took at the game that made me see all the accidents. Cool pics yah!=) congrats boys!

This semester we started off learning about acceleration, velocity and speed. Acceleration is measured by the change of velocity divided by the time it took. And speed and velocity are both measured by the distance traveled by the time traveled. The only difference between the two is that the velocity measures the direction of which the object travels. Well every since i've been driving I've had a first hand chance to change my velocity, speed, and acceleration of my car. I always thought that you could only accelerate by speeding up, but i never knew there was decreasing acceleration. The more i drive, the more i pay attention to the physics behind it now that I know it. I remember last week when my friends and I were driving to the basketball game, someone yelled. "Hey stop speeding!" and my classmate replied back, "I'm not speeding, I'm accelerating." Onlyif you know physics, you know whats the difference.=) Here is a pic of me and my little sister before we went in the car with my friends.
