<u>Answer:</u>
Of an object rolling down an inclined plane, the potential energy decreases as the kinetic energy increases.
<u>Explanation:
</u>
- An object that is located at a certain height is constantly being pulled down by the gravitational force of the planet.
- Thus, the potential of an object to come back to the ground when suspended freely is referred to as potential energy possessed by the object.
- When a spherical object is set free on an inclined plane, it automatically gains motion.
- As long as the object continues to roll down the inclination, it is said to have kinetic energy.
Answer:
European colonizers killed so many indigenous Americans that the planet cooled down, a group of researchers concluded.
