On Wednesday, we used a cart that shot a ball upwards while in motion to learn about projectile motion. When the spring was released and the ball was shot up while the cart was in motion, the ball didn't land on the table, it landed back in the cannon. We concluded that the X motion and the Y motion of an object are unrelated. Later, we used a contraption to release 2 balls at the same time, 1 that would drop straight down, and one that would be shot at a 90 degree angle. Surprisingly, the balls hit the ground at the same time.
Here are two links about the lesson that Mr. Burk recommended
