It is not rare for any motion to change quickly. When playing sports you should expect motions to change quickly.
It is rare for any motion to achieve perpetual motion. Perpetual motion is the hypothetical concept of a motion that continues indefinitely without any external energy source. This violates the laws of thermodynamics, specifically the conservation of energy, as it would require no energy input to sustain the motion indefinitely. In reality, all motion eventually slows down or stops due to factors such as friction, air resistance, and energy loss.
Motion is any movement or change. This can be position or time.

Inertia
The tendency of an object to resist any change in its motion is known as inertia.
Uniform linear motion is not accelerated because the speed of the object remains constant and there is no change in direction. Acceleration refers to any change in speed or direction of an object, and when there is no change in these factors, the motion is considered uniform and not accelerated.
It means any change in -- speed -- direction -- or both. Constant or 'uniform' motion means steady speed in a straight line.
Any action that is able to change the motion of a body is called a force. Forces can cause objects to accelerate, decelerate, change direction, or deform.
