5 the marble, dominoes, and all other objects in a rube goldberg machine are part of a system. how does this systems total energy change from the start to the end?\na it increases from the start to the end as the marble gains kinetic energy\nb it decreases from the start to the end as the marble loses potential energy\nc it remains the same from the start to the end\nd it transforms from potential energy to kinetic energy as the marble moves down the ramp and hits the dominoes

Answer

Answer:

D. It transforms from potential energy to kinetic energy as the marble moves down the ramp and hits the dominoes

Brief Explanations:

In a Rube Goldberg machine, the total energy of the system is conserved (ignoring small energy losses to friction/heat, which are not the focus of the core energy change described). At the start, the marble has gravitational potential energy due to its height. As it moves down the ramp, this potential energy converts to kinetic energy (motion), which is then transferred to the dominoes. Option A is wrong because total energy does not increase; option B is wrong because total energy does not decrease (only potential energy decreases, while kinetic increases); option C is technically true about total energy conservation but does not describe how the energy changes, which is what the question asks. Option D correctly describes the key energy transformation in the system.
