What is conserved in the collision of the bullet with the block?

The momentum of the block/bullet system is conserved. Therefore, the momentum before the collision is the same as the momentum after the collision.

Is a bullet being fired potential energy?

When a bullet is fired from a gun, its potential energy is converted into kinetic energy. When a bullet fired the chemical energy is in form of potential energy is converted in kinetic energy and heat thereby moving bullet out of the barrel. The sum of potential and Kinetic energy is known as Mechanical energy.

What happens to the energy lost by bullet while penetrating the wood?

When bullet gets imbedded in the wooden block, a part of the energy will be required to make a hole in the wooden block where the bullet will get embedded. This part of KE gets reduced from the total KE of wooden block embedded with bullet when it starts sliding on the rough surface.

Is energy conserved in ballistic pendulum?

A ballistic pendulum is a device for measuring a bullet’s momentum, from which it is possible to calculate the velocity and kinetic energy. In the case of a pendulum total mechanical energy is conserved. So kinetic energy of the pendulum (after firing) is fully converted to potential energy.

Why is energy not conserved in a ballistic pendulum?

The Ballistic Pendulum The bullet colliding with the wood block involves a non-conservative force (the friction that slows the bullet within the block), so the mechanical energy of the bullet + block system is not conserved.

Does bullet have potential energy?

A bullet before it is fired has a lot of potential energy, after it is fired it has a lot of kinetic energy. When it hits a target that kinetic energy is transferred to the target as more kinetic energy. Some energy is also lost to the surroundings as sound and heat.

What happened to the lost kinetic energy of the bullet?

-> Lost kinetic energy transforms into sound (the collision gives a sound), deformation (the bullet deforms) and heat (the bullet gains heat).

What type of energy does the bullet have before it hits the block?

kinetic energy
This is equal to the ratio of the kinetic energy of the block + bullet immediately after the collision to the kinetic energy of the bullet before the collision.

What is conserved in a ballistic pendulum?

Is momentum conserved while the bullet block combo is swinging?

The impact of the bullet with the block conserves momentum, but a great deal of kinetic energy is lost to things like heat and work ripping through wood fibers. The moving post-collision bullet and block combo swing on the string to some height, and in this, kinetic energy turns to potential.
