The Boomerang Ball

 

Last week after class I was on the train going home. I saw this kid tossing a ball up into the air and watched as the ball landed back into his hand. I began to wonder, why doesn't the ball fly to the back of the train if we are moving such fast speeds? Then I remembered the lab experiment that we saw in class, with the golf ball going up into the air and back into the cup. The ball was traveling at the same speed as the train. So when it left the kids hand, it was still traveling at the same speed as the train and so when it came back down is why if fell directly back into the kids hand. The link below is an excellent example of how velocity effects the our world.
