A ball is sliding on a rough surface, it will keep on sliding forever. 

Determine whether the given statement is true or false.

It is not necessarily true to say that a ball sliding on a rough surface will keep on sliding forever.

The motion of a ball on a rough surface will experience friction, which will eventually cause it to slow down and come to a stop. The amount of time it takes for the ball to stop sliding depends on the initial speed of the ball, the mass of the ball, the coefficient of friction between the ball and the surface, and other factors such as the surface area of the ball in contact with the surface.

In fact, if the surface is not perfectly level, the ball might not continue sliding at all, but instead start rolling or come to a stop altogether. So, the motion of a ball on a rough surface is subject to various forces and factors, and it cannot be assumed that it will keep sliding forever.
