* Type of glass: Tempered glass is significantly stronger than regular glass, but there are still variations in thickness and tempering quality.
* Impact point: Hitting the center of a pane is more likely to break it than hitting an edge or corner.
* Angle of impact: A direct hit is more powerful than a glancing blow.
* Tennis ball condition: A new, perfectly round ball will have a different impact than an older, deformed one.
General Information:
* Tempered glass is designed to shatter into small, blunt pieces, making it safer than regular glass. However, it can still break.
* A tennis ball travelling at high speed will have significant kinetic energy. This energy is transferred to the glass upon impact, and if it exceeds the glass's strength, it will shatter.
To give you a rough idea, consider these points:
* A professional tennis serve can reach speeds exceeding 150 mph. This is enough force to break some weaker types of glass, but not necessarily tempered glass.
* It's likely that speeds much higher than a typical serve would be needed to reliably break tempered glass.
* Specialized testing would be required to determine the exact speed needed for a tennis ball to break a specific type of tempered glass.
Important Note: It's not recommended to experiment with breaking glass, as it can be dangerous.
