Tokyo Dome Amusement Park

        On our second to the last day in Japan, we went to the Tokyo dome. In the area of the dome, there was a small amusement park that had about 4 rides. (three are pictured) the ferris wheel, the roller-coaster and the one that drops. The ferris wheel has centripetal force as it is going around and as you move around the whole thing, different forces are acting upon it. For the roller-coaster, energy is constantly being transferred from kinetic energy to potential energy and back to kinetic energy. It also is changing its velocity as the ride proceeds. As for the last ride, gravity and mg is used to pull the carts down. In addition, it is being secured by ropes which cause tension and creates a pulley. 

Japan= trains, trains and more trains

This spring break i went to Japan! in Japan, everybody uses trains and subways as their mode of transportation. Most of the time the trains are realllly crowded so you have to stand up and hold onto the handles (shown in the above picture). The reason why they have to hold on is all physics. Due to inertia, when the trains starts and stops, your body is wanting to either stay still or keep moving therefore your balance is thrown off. That is why you would need to hold onto something. Also, the trains in japan are powered electrically and magnetically.
