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

What is the definition for rolling friction?
Wheels, ball bearings, the Egyptians building the pyramids using tree trunks to move the stones. An example of rolling friction would be like a skateboard rolling on a sidewalk. car running up a hill. someone pushing a wheel barol A bowling ball
Is grinding up sea salt a exothermic or endothermic reaction?
exothermic
What is the type of heat reaction which occurs when heat is given off by the reaction?
Heat is released during an exothermic reaction.
Example of exothermic?
When concrete cures it warms up. Those hand warmers that heat up when they are opened up are exothermic. Desiccants when exposed to a lot off water.
Is condensation exothermic of endothermic?
Condensation is generally exothermic in that the material doing the condensing will be giving up thermal energy to do so. And giving up heat energy is the exit of thermal energy, hence the name exothermic. The atoms or molecules of this consate give up some of their kinetic energy, their energy of atomic or molecular motion, that thermal energy, to condense.
Is a ball rolling an example of acceleration?
Not necessarily. If it's rolling in a straight line on a smooth and level floor, then the acceleration is as good as zero. But if the ball is rolling up a hill, or down a hill, or around the groove in a roulette wheel, or through grass and slowing down, then there's substantial acceleration.
How do woodlices CURL up?
By rolling up their body into a ball
Why does a sled speed up going down a hill even if no one is pushing it?
Wrong category! It is acted upon by gravity - just the same as a ball rolling down a slope.
Kinetic energy refers to?
Kinetic energy refers to any energy related to motion. A ball rolling up a hill for instance is expending kinetic energy.
A ball rolling down an incline has its minimum speed?
The minimum speed for a ball rolling down an incline occurs near the top. Gravity will speed the ball up as it travels down.
What force will stop the ball from rolling after comes down a hill?
Conservation of Energy explains why it speeds up. It also explains why it rolls, due to the frictional force creating a torque.
Why does an organism have to provide energy for active transport?
The ATP hos to be provided because Active transport works against diffusion. its like the difference between a ball rolling down a hill (Passive Transport) and then having to push it up the hill (Active transport).
What does the idiomatic expression of rolling up mean?
Rolling up might mean to arrive. The image is of an automobile rolling up to the door. It also might mean rolling a cigarette (or anything that you smoke rolled up in a paper). A third meaning would be literally rolling something into a ball or tube, as in rolling up a newspaper into a tube.
When a ball is pushed up hill what are the forces?
FrictionGravity
How are cattle rounded?
By gathering them up like snow balls and rolling them down the hill. :)
What examples best describes using an inclined plane Rolling a wheel up a hill Riding a bike on a flat path unscrewing a lid from a jar taking a trunk down from a shelf?
Unscrewing a lid from a jar
Describe the motion of a ball in a typical sport?
Since a ball is a sphere the motion it makes is rolling. The rolling happens on the ground and in the air.
