please check my answser
.A car driver accelerates to a speed of 35 mph and then takes her foot of the gas pedal.Even though she does not press the brake pedal at any time,she eventually rolls to a stop.which of the following most likely causes the car to come to a stop?
A.kinectic energy is transformed into thermal energy.
B.electrical energy is transformed into potential energy.
C.potential energy is transformed into kinectic energy.(I pick this)
D.mechanical energy is transformed into chemical energy.
Yes, it is A !
Youre not correct... Its not C its A
To determine the correct answer, we need to understand the concept of energy transformations and how they relate to the car coming to a stop.
In this scenario, the driver has accelerated the car to a speed of 35 mph. Once she takes her foot off the gas pedal, the car begins to slow down until it eventually comes to a stop. This change in motion indicates a transformation of energy.
Based on the given options, let's evaluate each one:
A. Kinectic energy is transformed into thermal energy: This option suggests that the energy of motion (kinetic energy) is converted into heat energy. While some energy may be lost as heat due to things like air resistance or friction, it is not the main reason why the car comes to a stop in this scenario.
B. Electrical energy is transformed into potential energy: This option does not seem relevant to the given situation since there is no mention of any electrical input to the car.
C. Potential energy is transformed into kinetic energy: This option suggests that potential energy, stored in some form, is converted into kinetic energy, the energy of motion. In the case of the car coming to a stop, this option best explains the scenario. As the car slows down, its kinetic energy decreases, indicating a transformation of energy from kinetic energy back into potential energy.
D. Mechanical energy is transformed into chemical energy: This option is unrelated to the given situation as there is no mention of any chemical processes or reactions happening within the car.
Based on the information provided, it seems that option C, potential energy is transformed into kinetic energy, is the best choice as it aligns with the scenario described.
