The Science of Spinning

Increasing the mass increases the moment of inertia, symbolized by I, which is sometimes called the rotational inertia of an object. But the distribution of the mass is more important, i.e. distributing the mass further from the centre of rotation increases the moment of inertia by a greater degree. The moment of inertia is measured in kilogram metre² (kg m²)

The centripetal force is the external force required to make a body follow a curved path. Centripetal force is directed inward, toward the center of curvature of the path. The term centripetal force comes from the Latin words centrum("center") and petere ("tend towards", "aim at").

The centripukal force is the RipRider force of resistance-free drifting and spinning. How many spins til you lose your lunch? Follow this equation to find the scientific number: Your Age + Your Grade x 360 = centripukal force.

Did You Know?

The RipRider 360 was invented by Razor President’s 12 year-old son.

Other cool things invented by kids (one true, the rest assumed):
• Fake poop • Cheeto fingers • Prank calling • T.P.ing • Popsicles (TRUE!) - Frank Epperson invented the Popsicle in 1905 when he was only 11 years-old. Frank left his drink outside on the porch overnight with the stir stick in it. That night the temperature dropped below freezing, and left Frank's drink solid. That didn't stop him from tasting it. 18 years later Frank began his own business selling Epsicles in several fruit flavors. Later, his children changed the name to Popsicle. Over 1 billion Popsicles are eaten in the US each year. Out of the 30 flavors to choose from, orange has usually been the favorite.
