A hockey puck can actually serve as a good example of an object that is not experiencing any net force, but with an important clarification. A hockey puck that is sliding on ice at a constant velocity (with no friction acting on it) is experiencing no net force. In this scenario, the puck will continue moving in a straight line at that constant velocity according to Newton's First Law of Motion, which states that an object will remain at rest or in uniform motion unless acted upon by a net external force.
If the hockey puck were to come to a stop due to friction or hit an obstacle, then there would be a net force acting on it. So, to summarize, a hockey puck in motion with no friction or other forces acting on it is a correct example of an object not experiencing any net force.
