When the angle of inclination of on inclined plane is $\theta$, an object slides down with uniform velocity. If the same object is pushed up with an initial velocity u on the same inclined plane, it goes up the plane and stops at a certain distance on the plane. There after the body

Slides down the inclined plane and reaches the ground. With velocity "u"

Slides down the inclined plane and reaches the ground with velocity less than "u"

Slides down the inclined plane and reaches the ground with velocity greater than "u"

Stays at rest on the inclined plane and will not side down.
