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.

Newton's First Law of Motion

If a very smooth ball is rolled down an inclined surface with zero friction, the ball will continue to roll indefinitely for an infinite time, in an attempt to reach to the same height on the opposite hill!
