Unit 4- Projectile Motion

Unit 4
In class today the most important rule that we learned was axes are independent. This rule turned out to be most helpful when we did problems including projectiles like the experiment in the left picture. Our experiment was to shoot a ball out of a projectile and try to be precise and accurate with the place that the ball hit the ground. We had to use the axes are independent rule when we had to figure out distances. We then were given a test height and using the velocity of the cannon that we had already calculated has to mathematically figure out where we should place the paper bulls eye. My group was pretty close when we tested out our distance, but we had a few errors like angles, the position of our projectile cannon and not using the same ball every time.  It was a really fun activity.

We also did a fun pool activity today. A few of my classmates jumped in the pool and we video taped them doing it. Then we took the video and put it up in logger pro. In logger pro we graphed the persons acceleration, velocity and position and it was really interesting to see how the person moved.
