Final answer:
In a closed system, when an apple falls from a tree to the ground, the apple's beginning kinetic energy and ending gravitational potential energy are increasing.
Step-by-step explanation:
In a closed system, when an apple falls from a tree to the ground, the apple's beginning kinetic energy and ending gravitational potential energy are increasing.
To find the current flowing through the bulb of a flashlight, we can use Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R).
As the apple falls, its gravitational potential energy is converted into kinetic energy, causing the apple's speed to increase. The apple's beginning kinetic energy is zero because it starts from rest, but it increases as it falls due to the conversion of potential energy.
