Final answer:
In table tennis, a ball hitting the net and continuing over is called a 'let.' This only applies if the serve is otherwise good; otherwise, it's a fault. Knowledge of the sport's physics can enhance performance.
Step-by-step explanation:
When the ball hits the net in table tennis and still goes over to the opponent's side of the table, it is called a let. A let is typically called when the serve is otherwise good but the ball touches the net.
If the ball hits the net and does not continue over, it is considered a fault and points are awarded to the opponent. Understanding the dynamics of the impact in table tennis, such as hitting on the sweet spot and the application of physics concepts like momentum and rotational motion, is crucial for maximizing performance and minimizing the risk of injury like tennis elbow.
