Yes. Kinetic energy is a scalar (non-directional) and momentum is a vector. That means if you have two or more objects in motion their kinetic energies always add. But their momentums must be combined using vector addition and you might get zero. The simple case is two identical masses moving with equal but opposite velocities. Their total momentum is zero because their directions of motion are opposite.

Yes,
Take two objects of the same mass, A and B, whose velocities, VA and vb, are opposite
Ke = .5(m)(VA)^2 + .5(m)(vb)^2 =
Plug in some numbers, m = 1 kg, VA = 10 m/s, vb = -10 m/s
.5(1)(10)^2 + .5(1)(-10)^2 = 50 + 50 = 100 -- a positive number
momentum can be found using p = mva + mvb
so p = (1)(10) + (1)(-10) = 10 + -10 = 0

What is the total amount of kinetic energy in the particles of an object?
The total amount of kinetic energy in the particles of an object is the sum of the kinetic energy of each individual particle. The kinetic energy of a single particle is given by the equation KE = 0.5 * m * v^2, where m is the mass of the particle and v is its velocity.
What is a example of a momentum of zero?
An object at rest. Actually that's the only possible example for a single object. For two objects, you can have objects moving in opposite directions; for example, one may have a momentum of +100 units, and the other, a momentum of -100 units.
What is the four momentum of a photon and how does it relate to its energy and momentum?
The four momentum of a photon includes its energy and momentum in a single mathematical expression. The energy of a photon is directly related to its frequency, while its momentum is related to its wavelength. The four momentum of a photon helps describe its motion and interactions in the context of special relativity.
What is the kinetic energy of a gas molecule proportional to according to the kinetic theory?
The kinetic energy of a gas molecule is proportional to its temperature. According to the kinetic theory of gases, the average kinetic energy of gas molecules is directly proportional to the absolute temperature of the gas.
According to the kinetic theory what is the kinetic energy of a gas molecule proportional to?
The kinetic energy of a single gas molecule is not proportional to anything. The average kinetic energy of gas molecules is proportional to their absolute temperature.

Does an object have to be heavy in order to have momentum?
No. Even a single electron has momentum.

What is a total inelastic collision?
A totally inelastic collision is a type of collision in which two objects collide and then stick together, moving as a single combined mass after the impact. In this type of collision, kinetic energy is not conserved, although momentum is conserved. The total kinetic energy after the collision is less than the total kinetic energy before the collision due to the conversion of some energy into other forms, such as heat or deformation. Total inelastic collisions are characterized by maximum energy loss compared to other types of collisions.
What can electrical energy transform into?
nowadays to every single type of energy. such ac magnetic energy, chemical energy, kinetic energy,etc
What are the conversations?
Energy conversions is the process of energy changing form within a single object. For example, when you release a pendulum, the potential energy it had while being drawn upwards is changed into kinetic energy or the energy of movement. The total amount of energy is kept the same, but is simply changing the amount of energy each type had.

Conservation of linear momentum exp?
Linear momentum is mass times velocity. For a single point object, momentum is conserved, because the object will continue to move at a constant velocity. Nor will its mass change either. For a group of objects, too: When momentum is transferred, for example during a collision, any momentum lost by one object is gained by another. The total momentum remains constant.
Two objects collide and stick together. how does the total momentum change?
The total momentum after the collision remains the same as before the collision. This is because momentum is conserved in a closed system, even when objects stick together. The momentum of the two objects is simply combined into a single object after the collision.
