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.
The bullet fired from a gun has greater horizontal acceleration. For vertical acceleration, they are both the same.
I used gelatin or a large water tank.
The recoil of a bullet being fired from a gun is a good example, the action force is the gun pushing the bullet away from the gun and the reaction force is the bullet pushing back against the gun (recoil).
When a bullet is fired into the sky, it will eventually stop becasue it has run out of energy and fall back to the ground.
That would depend on the mass of the bullet, the bullet's velocity when it left the barrel of the gun, and from how high up the bullet was fired from.
Yes, a bullet can potentially knock someone over with the force of impact. However, there are many variables that can influence the effect of a bullet, such as the caliber of the bullet, the distance it is fired from, and where it strikes the body.
Yes.
Wilkes Booth John.
No. The bullet will actually travel much slower due to wind resistance.
Yes
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
When a bullet is fired upwards vertically, it gains potential energy as it moves against gravity. This increase in potential energy comes at the expense of its initial kinetic energy. Eventually, the bullet will reach its maximum height and then begin to fall back towards the ground, converting its potential energy back into kinetic energy.
