Hereof, can a ball roll forever?
So the ball should roll on forever.The ball only stops rolling because an external force(friction) causes the ball to stop.
One may also ask, why does an object moving on a smooth surface stops by itself? The object doesn't stop by itself; itstops because of friction between itself and thesurface. If you said “frictionless,” itwould slow down because of air resistance, but itwould never actually stop, because the air resistanceforce decreases as its speed decreases.
Beside above, why do objects eventually stop moving?
Newton's first law of motion states that "Anobject at rest stays at rest and an object inmotion stays in motion with the same speed and in thesame direction unless acted upon by an unbalanced force." Movingobjects, so it was believed, would eventually stopmoving; a force was necessary to keep an objectmoving.
What causes a ball to roll?
The ball rolls because: the friction presentbetween the surface pushes the atoms/particles in contact withsurface or ground backwards, hence with centre of mass moving in adirection, the ball's bottom surface(ie. The surface incontact) moves in opposite direction or backwards, causing theball to roll.
