Why does a bullet when fired against a glass window pane make a hole in it and the glass pane will smash it?

when a bullet strikes the glass pane with a high velocity, the larger part of the glass plane do not get enough time to share the momentum due to inertia of rest and only that part which is in contact of the bullet is blown off according to the law of conservation of momentum
But when a slow moving stone strikes the glass plane a larger part of the glass is able to share the momentum and therefore it smashes the glass

Why does a bullet fired at a glass window makes a hole but doesn't crack while a stone striking it will smash it?
It's all down to surface area and speed ! The bullet is tapered to a point or rounded tip - the stone is bulky and irregular in shape. The bullet is travelling faster than sound - the stone travels at just a few feet per second.
Why does a bullet makes a hole when it is fired at a glass?
Glass is usually made shatter proof in order too prevent long sharp pieces of glass injuring people. This is done by either applying a clear sheet of plastic too the glass, or the glass sheet is heated till just below the softening point and then cold air is blasted onto the glass, this way when the glass breaks into small chunks which would explain why in some cases the bullet only punctured a hole instead of shattering the whole sheet of glass.

Why does a stone shatter glass while a bullet makes a neat hole?
A bullet travels at really high velocity and therefore the glass does not have enough time to bend due to the force and shatter instead the bullet just damages the area it gets in contact with and thus making a hole in the glass. Whereas a stone travels at a low velocity and the glass has enough time to bend and shatter
Can glass give protection against AK 47?
Bullet resistant glass will. Regular window glass- no.
Why does a bullet when fired against a glass window pane make a hole in it and the glass pane will gets broken?
At the point of impact, the glass immediately infront of the projectile is powerded. This causes localized stress in the rest of the sheet, as can be seen by the spider web around the hole. The rest of the cracks radiating from the site are where the residual energy from the impact are distributed.
Why does a small bullet can make a clear hole in a glass window but a big stone can only crack it?
I would say this has to do with velocity of the bullet.(speed)

From ordinary glass to bullet resistant glass?
A bullet resistant glass screen is made of a number of glass sheets which can be standard thicknesses window glass, separated by air gaps. Security films, preferably made of polyester, are provided on the front and rear surfaces of the glass sheets. A pressure sensitive adhesive can be used to adhere the security films to the glass sheets. The resistance off the screen to penetration by a bullet is increased by increasing the thickness of the air gaps. There is also a metal net on both sides of each glass pane to stop it shattering if a bullet hits it.
What is the element formula of bullet proof glass?
The Scientific name for Bullet Proof Glass is Bullet Resistant Glass. It is referred to as Bullet Resistant Glass in the Industry as there is no such glass that can stop every bullet. A series of bullets that hit within a small area of the Bullet Resistant Glass will eventually project right through the glass.
Do airplanes have bullet proof glass?
No airplanes do not have bullet proof glass.
What products and spray products are need to make your car bullet proof?
I do not know of any spray products that make a car bullet proof, but there is bullet-proof plastic that form to fit the window type of a certain car, and some bullet proof glass.
Can bullet proof glass withstand a 1000 fps bullet?
It depends on the thickness of the glass and the muzzle energy of the bullet, not just the velocity.
