The ball of dough hits the floor and does not rebound. Describe the energy transfers taking place from when the dough is dropped to after it has hit the floor.
You should refer to energy stores as well as transfers between energy stores at these stages.
before the dough is dropped
just before the dough hits the floor
after the dough has hit the floor
can anyone answer this question?

The ball of dough does not rebound after it hits the ground because its kinetic energy store decreases, ie; most of its kinetic energy is transferred to the surroundings as thermal energy and sound energy.

When the dough is held at a certain height from the ground; before the dough is dropped the energy of the dough is stored as gravitational potential energy.When the dough is dropped, it starts to fall freely and the force of gravity that acts on the object causes the gravitational potential energy to be transferred to its kinetic energy. This makes the dough fall faster as it falls down.Just before the dough hits the ground, its gravitational potential energy is fully transferred to its kinetic energy store.As the dough hits the floor, its kinetic energy store decreases as most of it gets transferred to the surrounding as thermal energy and sound energy. Some of the kinetic energy is also lost through deformation when the dough changes shape.

When the ball goes down its mechanical energy is conserved, ust before touching the ground all the energy is kinetic

When the ball touches the floor, energy has been converted into potential and heat, by the deformation of the ball.

Explanation:

When the ball goes down its mechanical energy is conserved, this is the power energy due to the height it is converted into kinetic energy to medicad that falls, just before touching the ground all the energy is kinetic.

When the ball touches the floor, the kinetic energy is not conserved, but if we define a system formed by the ball and the floor, the amount of movement is conserved, this being an inelastic shock, because the bla and the floor are stuck, so which energy has been converted into potential and energized and heat by the deformation of the ball.

Consequently all the mechanical energy that the ball brings before reaching the ground was converted into potential energy and heat during the crash.

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.

Some material consisting of a collection of microscopic objects is kept at a high temperature. a photon detector capable of detecting photon energies from infrared through ultraviolet observes photons emitted with energies of 0.3 ev, 0.5 ev, 0.8 ev, 2.0ev, 2.5ev, and 2.8ev. these are the only photon energies observed. (a) draw and label a possible energy-level diagram for one of the microscopic objects, which has four bound states. on the diagram, indicate the transitions corresponding to the emitted photons. explain briefly. (b) would a spring–mass model be a good model for these microscopic objects? why or why not? (c) the material is now cooled down to a very low temperature, and the photon detector stops detecting photon emissions. next, a beam of light with a continuous range of energies from infrared through ultraviolet shines on the material, and the photon detector observes the beam of light after it passes through the material. what photon energies in this beam of light are observed to be significantly reduced in intensity (“dark absorption lines”)? explain briefly.
