Which situation is the BEST example of inertia? An old lady uses a walker and is able to cross the street. A rocket thrusts its booster and lifts off the launching pad. A rock is thrown vertically up in the air and it falls back to the earth. You go down a steep roller coaster and it feels like your stomach is going up into your throat.
