The rock on the ground has more kinetic energy compared to the feather floating through the air, due to the force of gravity.
Kinetic energy is the energy of motion, and a moving object has kinetic energy. Potential energy, on the other hand, comes in several forms, such as gravitational potential energy. When comparing a feather floating through the air and a rock on the ground, we can say that the rock has more kinetic energy.
This is because the rock, when dropped, falls to the ground due to the force of gravity, gaining kinetic energy in the process. The feather, on the other hand, is floating through the air and not experiencing the same gravitational pull, thus having less kinetic energy than the rock.
