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?

    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.
