Which of the following statements about energy is true? I. Kinetic energy cannot be transformed into another type of energy. II.
asambeis [7]

Kinetic energy is the energy the body possesses due to its motion. Kinetic energy is a kind of mechanical energy, as well as potential energy. All bodies that move linearly or rotate possess a certain kinetic energy.

Potential energy is the energy that an object has due to its position relative to another object. When we stand on the top of the building, we have more potential energy than when we are at the bottom, because the earth is attracted by the force of gravity.

When the body falls, it at the beginning of the fall has potential energy due to the force of gravity, and therefore falls, and then the potential energy turns into a kinetic, because the body moves in the fall.

When we kick the ball upwards, it moves upward, because it has kinetic energy, until it stops at one point, since there is no kinetic energy of motion, and only at that moment the kinetic energy turns into a potential, at that moment the ball is stopped, until it starts to fall again.

Correct answers are II. and III.
