Why don't people fall off roller coasters? Kuya Kim explains

Ever wondered why people don't fall off roller coasters despite how fast it moves?

In Monday's episode of #KuyaKimAnoNa on "24 Oras," Kim Atienza explained that it's because of inertia.

"Kahit malakas ang pull of gravity dahil sa constant speed, nakadikit ang pwet mo doon sa upuan 'pag ito'y umiikot," Kuya Kim said.

["Even though the pull of gravity is strong because of constant speed, your behind is stuck on the seat when the roller coasters goes in loops.")

Also, did you know that roller coasters in theme parks don't have engines?

"Ang mga roller coaster ay wala namang motor kahit napakabilis ng kanilang takbo. Hinihila 'yung roller coaster sa highest point nito—'yon ang kanyang potential energy," he said.

["Roller coasters don’t have motors even though they go fast. The roller coasters are pulled to its highest point—that's its potential energy."]

"'Pag release nito, kinetic energy kaya napakabilis ng kanyang ikot. Kahit mag loop, 'di tumitigil."

["When it's released, that's kinetic energy, that's why it travels fast. Even if it loops, it doesn't stop."]

While riding the Flying Fiesta, meanwhile, Kuya Kim gave a tip on how one can avoid feeling dizzy.

"Ang utak natin, nalilito sa nakikita ng ating mata so ang pinakamagandang paraan para 'di ka mahilo ay pumikit ka," he said.

("Our mind gets confused about what the eyes see so the most effective way to not get dizzy is to close your eyes.")

Under Alert Level 3, amusement parks are allowed to operate with a limited capacity, said Department of the Interior and Local Government (DILG) Usec. Epimaco Densing III.

"Kung indoor po ito, up to 30% capacity, but only for vaccinated individuals. Kung outdoor theme parks naman ay 50% capacity. Bawal pa rin po dalhin ang mga bata," he said.

["If it's indoor, up to 30% capacity, but only for vaccinated individuals. If outdoor theme parks, 50% capacity. Children are still not allowed to visit."]
