Explain why a glass pane is shattered when a flying pebble hits it?

Answer 1

The flying peeble imparts momentum(force * time) to the pane during collision and as glass is a amorphous solid,it donot have cleavage property and gets shattered

Answer 2

When a flying pebble hits a glass pane, it creates a point of impact where the force is concentrated. This force is strong enough to overcome the cohesion between the glass molecules, causing the glass to shatter into fragments. The sudden release of energy from the impact spreads through the glass, causing it to break apart.
