Responses
The energy on the macroscopic scale and the energy on the molecular scale both decreased.
The energy on the macroscopic scale and the energy on the molecular scale both decreased.
The energy on the macroscopic scale and the energy on the molecular scale both remained constant.
The energy on the macroscopic scale and the energy on the molecular scale both remained constant.
The energy on the macroscopic scale increased, and the energy on the molecular scale decreased.
The energy on the macroscopic scale increased, and the energy on the molecular scale decreased.
The energy on the macroscopic scale decreased, and the energy on the molecular scale increased.
The energy on the macroscopic scale decreased, and the energy on the molecular scale increased.
The correct statement describing the situation when a ball rolling on the floor comes to a stop is:
The energy on the macroscopic scale decreased, and the energy on the molecular scale remained constant.
The correct statement would be: The energy on the macroscopic scale decreased, and the energy on the molecular scale remained constant.
When a ball is rolling on the floor and comes to a stop, it is experiencing frictional forces that act to slow it down and eventually bring it to rest. These frictional forces convert the kinetic energy of the ball into other forms of energy, such as heat and sound. This conversion of energy causes a decrease in the macroscopic scale energy of the ball, since its kinetic energy decreases as it slows down and eventually stops.
However, on the molecular scale, the energy remains constant. The molecules that make up the ball and the floor are still in motion, even when the ball comes to a stop. The kinetic energy of these molecules remains unchanged, while the macroscopic scale energy decreases due to the conversion of kinetic energy into other forms of energy.
