2D Kinematics and Projectile Motion!

We have learned about the basics of vectors and how to use them, and this week, we learned a lot more!
First, we learned that equivalent vectors are vectors that have the same direction and magnitude! We also learned about the Vegas rule which relates to the saying "what happens in Vegas stays in Vegas". The Vegas rule states that all axes are independent: what happens on the x axis stays on the x axis, and what happens on the y axis stays on the y axis! During our last class this week we talked about the ball toss again and how it relates to the Vegas rule. The x and y axes are independent. We learned that the x axis is constaaaaaaaaant because it is moving at a constant velocity. The y axis is accelerating because a curved graph shows acceleration (fast slow stop slow fast). The picture below shows the y axis of the path of the ball my mom is throwing.
