Sure. A Bowling ball sitting on the top shelf in the closet has a great deal
of potential energy. But it's not moving, so its momentum is zero.
And let's not forget the heat energy in a glass of water, the chemical energy
in a gallon of gasoline, or the electrical energy in a battery ?
Any mass can be expressed in terms of energy, according to the famous formula, E=mC^2.Thus, any mass (m), having a momentum will always have some energy associated with it.
Momentum = (mass) x (speed) Kinetic Energy = 1/2 (mass) x (speed)2 It looks like the only way a body can have zero momentum is to have either zero mass or else zero speed, and if either of those is zero, then that makes the KE also zero as well, too. So the answer to the question is apparently: no.
Yes, the kinetic energy of a system can be changed without changing its momentum if there is an external force acting on the system. For example, if friction is present, kinetic energy can be converted to other forms (such as heat) without affecting momentum.
If the velocity of a body is doubled, its kinetic energy will increase by a factor of four. This relationship is because kinetic energy is proportional to the square of the velocity. Additionally, the momentum of the body will also double.
You need to frame your question better. A movinng object will not change momentum unless a force acts upon it. A force could be supplied by many things including a collision, gravity, friction What evr happens, energy will be conserved. If friction through air reduces a body's momentum, then the momentum of the of the body will be transfered to momentum of the air particles (which is ultimately seen as heat, and is infact an increase in speed and hence momentum of the molecules
yes. a body can have energy without momentum also. consider a body at a height 'h' m above the ground level , potential energy contained is = mgh but , as the velocity is 0 we can consider that the momentum of the body is 0
No.

Momentum is the product of mass and velocity. Energy is the capacity of a body to do work.
No.

A body can't have kinetic energy without also having momentum. But it can have any otherkind of energy ... the ones that don't involve motion. A charged battery, a stretched rubber band,a can of gunpowder in a drawer, a bowling ball on a high shelf, a gallon of water behind HooverDam on a calm day, and a coil of wire carrying an electric current, all have plenty of energy butno momentum.

Momentum is the product of mass and velocity. Kinetic Energy is the product of mass and velocity squared. As you can see, since Kinetic Energy is derived from mass and velocity, and Momentum is derived from mass and velocity, you cannot have one without the other.

No, it cannot. In the case of an object moving in the free space (no forces acting on the object) the energy consists of only the kinetic energy which is proportional to squared momentum. Thus, if the object has a momentum it has an energy to. Basically an object possesses some energy in any kind of time, and it might happen that the energy is zero. It doesn't mean that it has no energy. It means that the object has energy equals zero (which is not the same).
