Answer:
1) Roller coaster loops are never circular...why do you think that is?:
This force is called the Centripetal Force.
Newton's first Law of Motion of motion tells us that, without this force, the coaster would like to travel in a straight line and at constant speed. The centripetal force is pushing the coaster around in a circle. It is your body's (equal and opposite) reaction to this force, often referred to as the Centrifugal Force, that explains the feeling you get .There is a force (provided by the rails), that is pushing the trucks of the coaster towards the centre of the loop.
t of being squashed into your seat (Newton's third Law of Motion)
2. Riding Big Thunder Mountain Railroad at Disney World could help dislodge kidney stones....why do you think that is?:
Riding the Big Thunder Mountain Railroad roller coaster at Disney World could help ease the passage of small kidney stones. Kidney stones are hard masses of minerals that form in the kidneys. They can range in size, from a tiny grain of sand to, in extreme cases, the size of a golf ball. Patients with kidney stones don't always need treatment, because the stones can pass out of the body on their own, but the process of passing them can be quite painful. Riding the Big Thunder Mountain Railroad roller coaster at Disney World could help ease the passage of small kidney stones, according to the new study because of 'The intense ride helps get rid of them'.
