Potential Energy
At the top, since potential energy is referred to an objects location, the highest the object the highest its potential energy.
A basketball rolling across a flat floor has translational and rotational kinetic energy. There's a force of gravity pulling the ball down towards the floor, and a reaction force pushing the ball up away from the floor.
The ball has the highest potential energy at its maximum height (15m in the air). At the beginning, the ball has only kinetic energy and no potential energy. But as the ball travels upward, kinetic energy is converted into potential energy. When the ball changes direction, there is no kinetic energy, as all of it is now potential energy. As the ball returns back down, potential energy is converted back into kinetic energy.
kinetic energy
It is conserved. The potential energy of the ball sitting at the top of the hill is converted into kinetic energy of the rolling ball.
No, a ball sitting at the top of a hill has potential energy, but once that ball starts to roll down the hill it's potential energy is converted to kinetic energy, the energy of motion. I disagree 100% with this edit. If a ball is rolling down hill and is say half way down it still has potential energy ready to be converted to kinetic energy So the answer is YES
A bowling ball rolling off a shelf and falling down onto a trampoline.
Potential Energy

Yes, because potential energy is energy stored but kinetic is energy in motion.
The act of rolling is showing kinetic energy because it is movement, but we should always look at energy change. As you go down hill, potential energy is converted to kinetic energy.

kinetic energy
The same as it's potential energy
