Vectors

A vector is described as how far as how far and in what direction something moves. The difference between vectors and distance is that vectors show what direction it is moving. For my example I took a picture of a tennis ball in motion, which you can barely see in the middle of the screen. The ball is accelerating 9.8 m/s squared because of gravity and toward the negative direction in relevance to the x- axis.

Acceleration

This week we have been working on acceleration a lot. We have done the ball toss lab and defined several graphs and what they mean. The picture I took is from a pool table. The cue ball was shot and broke up the balls in the middle. The cue ball accelerated toward the rest of the balls and came to a stop by accelerating backward. The cue ball then transferred the force to the other balls causing them to accelerate in different directions. The other balls then either fell in a pocket or hit the rails causing them to slow down and then stop. This happened because the balls accelerated in the opposite directions causing it to slow down or stop.
