are you 100% sure?
Apologies for the confusion in my previous response. Given the scenario described, the correct answer is: potential → mechanical → kinetic.
The correct answer is:
potential → mechanical → kinetic
The correct answer is: potential → mechanical → kinetic.
Explanation:
When Rebecca climbs the ladder of the water slide, she is gaining potential energy. Potential energy is the energy an object possesses due to its position or state. In this case, Rebecca is gaining potential energy because she is being raised to a higher position on the slide.
Once Rebecca reaches the top of the slide and slides down, her potential energy is converted into mechanical energy. Mechanical energy is the total energy possessed by an object due to its motion or position, and can be in the form of kinetic energy (motion) or potential energy (position). In this case, the mechanical energy is in the form of kinetic energy.
Finally, as Rebecca slides down the slide and enters the pool, her kinetic energy is converted back into potential energy. This happens because her motion (kinetic energy) is being slowed down by the water resistance, causing her to come to a stop. At this point, she has potential energy again, but this time due to her position in the pool.
Therefore, the energy changes during her time on the slide can be described as: potential → mechanical → kinetic.
