\nThe correct answer is Its kinetic energy decreases while potential energy increases. This describes the energy transformation as an object moves against gravity and slows down.
\n<\/section>\n
\nAt the rest position (lowest point), the swing has its maximum speed and thus maximum kinetic energy (assuming negligible energy loss). As it rises, its height above the lowest point increases, causing its gravitational potential energy (PE = mgh) to increase. Simultaneously, the swing slows down as it moves upwards against gravity, causing its kinetic energy (KE = 1\/2 mv^2) to decrease.
\n<\/section>\n
\nAccording to the principle of conservation of mechanical energy (in the absence of friction and air resistance), the total mechanical energy (sum of potential and kinetic energy) remains constant. Thus, any decrease in kinetic energy is compensated by an equal increase in potential energy, and vice versa.
