If a stone is dropped with an initial gravitational potential energy of 100 J but reaches the ground
with a kinetic energy of only 75 J, this is a violation of the principle of conservation of energy.

Question

Quizplus · Accepted Answer

The difference in energy (25 J) could be accounted for by other forms of energy such as heat due to air resistance, indicating no violation of the conservation of energy principle.
