Gravity Explained! We rode the Yukon Striker for SCIENCE!

Ever since Laura was a little kid, she’s been obsessed with Roller Coasters! But it wasn’t until recently that she realized most roller coasters run almost entirely on gravity. She decided to take Daniel and Lucas back to Canada’s Wonderland to ride the Yukon Striker, the world’s highest, longest, and fastest dive coaster. At Wonderland, they meet the head of maintenance and construction at Canada’s Wonderland, Peter Switzer. Switzer talks about the fact that most people think roller coasters have an emergency break, but because they run on gravity they cannot stop. Laura gives a quick refresher on gravity! Gravity is the force that pulls all things together, and every piece of matter in the universe has gravity. But how did we find this out? Well thanks to physicists, Galileo Galilei, Sir Isaac Newton, and Albert Einstein. Galileo dropped two bowling balls off the Tower of Pisa to confirm that all objects will fall at the same rate regardless of their mass. Sir Isaac Newton formulated the law of universal gravitation, which states that all particles in the universe attract all other particles. Albert Einstein helped revolutionize our understanding of gravity with the theory of relativity, and helped us understand that matter actually curves the fabric of space and time. Laura shows a quick experiment to visualize gravity and how it bends space time. This also shows how planets take orbit. Laura asks Peter a bit more about G Force, which is a measurement of acceleration. The force of gravity on earth is 9.81 m/s squared, and this is equal to 1 G. When you’re changing directions on a roller coaster, you might feel heavier or lighter, and this is why G Force is related to how heavy you feel. Your mass is the same everywhere in the universe, but your weight will change depending on the gravitational force you’re experiencing. Astronauts in space may experience microgravity, or zero Gs, as though they are in constant freefall. Laura talks briefly about the Flip Flap Railway in Coney Island in the late 1800s. Older roller coasters has circular loops that exposed rides to extremely high G Forces. Modern roller coasters use tear drop loops, or clothoid loops that make for more comfortable rides. Finally, Laura, Lucas and Daniel make it to the top of the Yukon Striker. They dive down 245 ft and have the time of their life, experiencing up to 3.5 Gs. Next up….
