What portion of the total kinetic energy of a rolling object is translational energy?

If an object is rolling without slipping, then its kinetic energy can be expressed as the sum of the translational kinetic energy of its center of mass plus the rotational kinetic energy about the center of mass. The angular velocity is of course related to the linear velocity of the center of mass, so the energy can be expressed in terms of either of them as the problem dictates, such as in the rolling of an object down an incline. Note that the moment of inertia used must be the moment of inertia about the center of mass. If it is known about some other axis, then theparallel axis theorem may be used to obtain the needed moment of inertia.

Is it possible to change translational kinetic energy of an object without changing it rotational energy?
yes
Why is a rock on the top of a hill kinetic energy?
A rock on top of a hill has potential energy, not kinetic energy. If it starts rolling down the hill then the potential energy transforms to kinetic energy.
Temperature is relative to the energy of the molecules?
Increasing temperature will increase molecular speed.An object with less massive molecules will have higher molecular speed at the same temperature.When kinetic temperature applies, two objects with the same average translational kinetic energy will have the same temperature. An important idea related to temperature is the fact that a collision between a molecule with high kinetic energy and one with low kinetic energy will transfer energy to the molecule of lower kinetic energy.
What is a form of kinetic energy that occurs within a molecule when the bonds are stretched or bent a translational b rotational c vibrational d internal?
Vibrational.
What is the mean translational kinetic energy of the gas molecules?
The expression for gas pressure developed from kinetic theory relates pressure. The more familiar form expresses the average molecular kinetic energy, energy used here is limited to the translational kinetic energy of the molecules.
A basketball rolling across a flat floor has 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.
What kind of energy does a rolling toy have (rolling toy)?
It has kinetic energy.
Is it possible to change translational kinetic energy of an object without changing it rotational energy?
yes
Is a wagon rolling down the side walk kinetic energy or potential energy?
kinetic energy
How does a bowling ball being rolled down a bowling alley have kinetic energy?
Kinetic energy is the energy a moving body - in this case, the bowling ball - has. The ball actually has two forms of kinetic energy: rotational and translational. The rotational energy is the energy of it's spin, and the translational energy is the energy of it's motion towards the pins.
What is translational energy?
The kinetic energy of an object is the energy which it possesses due to its motion.Translation kinetic energy is energy due to motion along a path (as opposed to rotational kinetic energy, which energy do the motion created when an object rotates, or changes its orientation in space.)
What are the four types of kinitec energy?
Translational, rotational, rolling (not sure if this counts), and vibrational.
Why does a Screw takes less forces to move into wood than a nail?
a screw possesses both rotational kinetic energy and translational kinetic energy while a nail possesses only translational kinetic energy as it moves through the piece of wood hence the screw moves faster since its motion is backed by more energy than the nail.
What kind of energy a rolling toy have?
It has kinetic energy.
What kind of energy does a rolling toy?
It has kinetic energy.
What kind energy does a rolling toy have?
It has kinetic energy.
What is one example of rolling friction?
rolling paper becuse it produce kinetic friction and kinetic energy
