They are in the inverse relationship between potential energy, and kinetic energy.
The energy of the body by the virtue of its motion is known as the kinetic energy of the body. It is defined as the product of half of mass and square of the velocity.
According to the law of conservation of energy, total energy is defined as the sum of kinetic energy and potential energy.
Total energy = kinetic energy+potential energy
At the top of the U ramp, potential energy is greatest, while kinetic energy is least. The potential energy is the lowest and the kinetic energy is the largest at the bottom of the U ramp.
Hence, PE and KE have an inverse relationship.
