If a marble rolls along the inside of a semicircular track how does it leave the track?
November 13th, 2009 | by admin |Assuming a frictionless surface and a marble being rolled on a flat surface around a semicircular track (think half of an o), how does the marble leave the track once it reaches the end? Does it leave straight, curve outwards away from the track, or curve inwards as if it were still on the track?
Newton’s first law states that "Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it".
When the ball leaves the track it will be free of any forces influence, so it will simply travel straight in what ever direction it was in at the moment it leaves the track.
