What causes smartphone glass to break

The video tutorial explains how energy converts into surface energies or cracks, and highlights two factors—hardness and strength—that prevent phones from shattering. It discusses how falling face down can spread impact stress, potentially causing unseen damage. The tutorial also introduces new glass technology that enhances resistance, allowing glass to withstand greater weight and height in standard tests.

What happens to most of the energy when a phone is impacted?

• It converts into surface energies or causes cracks.

• It turns into sound energy.

• It dissipates into the air.

• It is absorbed by the phone's battery.

Which factor helps a phone resist scratches?

• Weight

• Hardness

• Color

• Flexibility

What is the role of strength in phone durability?

• To prevent the phone from overheating

• To prevent the phone from shattering

• To make the phone lighter

• To enhance the phone's color

What can happen when a phone falls face down?

• It will always shatter.

• It bounces back without any damage.

• It spreads the stress of impact but can still cause unseen damage.

• It becomes more resistant to future falls.

How does new glass technology improve phone durability?

• It makes the phone waterproof.

• It enables the glass to withstand more weight and height in tests.

• It changes the color of the glass.

• It allows the phone to float.
