Page 460- image of a rollercoaster full of excited riders plunging down its first drop and the text written over the image is "As it falls, the coaster converts potential energy into kinetic energy." Page 461, top- A diagram of a rollercoaster with car of riders making its way up a lift hill. Above the image, the following text is written "Releasing energy: A roller coaster goes through a series of exchanges between potential and kinetic energy." In the diagram, when car-riders start, the following text is written: "A cable pulls cars to the top of the lift hill. During the climb, the coaster builds up potential energy." When rider takes it first plunge, the following text is written: "Potential energy rapidly turns into kinetic energy during the first plunge." When rider reaches down, the following text is written: Kinetic energy reaches a maximum as the coaster reaches the bottom of the first hill." When rider takes its second loop, the following texts is written: "The second loop has a lower peak than the first because the coaster's energy is reduced by friction." Bottom right- image of a group of workers in safety gear installing a rollercoaster and the following text is written below the image: "Coaster forces During a ride, you are kept in your seat by the safety bar and the force of the seat pushing on you. The coaster also exerts large forces on the track, which must be inspected daily for structural damage." Bottom Left- An early loop ride in Coney Island, NY. The cable car is going around the loop and the following text is written below the image: "Acceleration An early loop ride at Coney Island subjected riders to about g's (12 times the acceleration due to gravity). For safety reasons, most modern rides do not exceed 5 g's."
