Answer: As an object falls its potential energy decreases, while its kinetic energy increases. The decrease in potential energy is exactly equal to the increase in kinetic energy.
Explanation:
Newton's third law (for every action, there is an equal and opposite reaction) means that in every interaction (in this case, that of the objects in the image), there is a pair of forces acting on the two interacting objects. <span>When you sit on a chair, your body exerts a downward force on the chair and the chair exerts an upward force on your body. There are two forces resulting from this interaction - a force on the chair and a force on your body. This is embodied in the image by the two objects exerting force on each other (indicated by the arrows).</span><span>

Answer:
The particles move faster, and their average kinetic energy increases.
Explanation:
When the temperature of gases increases the reaction rates will increase. Molecules of gases will be furnished with higher kinetic energy. Kinetic energy is directly proportional to temperature. Increase in temperature causes the frequency of ordinary collisions and effective collisions per unit time to increase. This leads to a surge in kinetic energy too.
