What is the difference between momentum and kinetic energy and why is it that kinetic energy can be changed in to other forms of energy but momentum cant?

Firstly, momentum is not a form of energy; the question seems to imply so.
Kinetic energy is the energy possessed by a moving object. That energy is provided by a source, and can be removed from the object because energy possessed by an object is not an inherent part of that given object.
Momentum is a property of mass; momentum is inherent in the mass of the object, and cannot be removed or put somewhere else, only altered.

When kinetic energy doubled what happens to momentum?
Momentum increases
What is the mathematical relationship between momentum and kinetic energy of the body?
Kinetic energy is the sum of all the parts of momentum: p=mv >function for momentum ∫ p=∫ mv.dv >integrate both sides with respect to velocity ∫ p=.5mv²=Ek >results in formula for kinetic energy
What does not have the same units as the others Kinetic Energy Momentum Potential Energy or Work?
momentum
When an action and reaction occur momentum is usually lost?
No. Total momentum before and after the collision is the same. Some kinetic energy can be lost - but not momentum.
Can potential energy ever be less than kinetic energy?
The answer to both of your questions lies in the different nature of both quantities, momentum and kinetic energy. Momentum is a vector, kinetic energy is a scalar. This means that momentum has a magnitude and a direction, while kinetic energy just has a magnitude. Consider the following system: 2 balls with equal mass are rolling with the same speed to each other. Magnitude of their velocities is the same, but the directions of their velocities are opposed. What can we say about the total momentum of this system of two balls? The total momentum is the sum of the momentum of each ball. Since masses are equal, magnitudes of velocities are equal, but direction of motion is opposed, the total momentum of the system of two balls equals zero. Conclusion: the system has zero momentum. What can we say about the total kinetic energy of this system? Since the kinetic energy does not take into account the direction of the motion, and since both balls are moving, the kinetic energy of the system will be different from zero and equals to the scalar sum of the kinetic energies of both balls. Conclusion: we have a system with zero momentum, but non-zero kinetic energy. Assume now that we lower the magnitude of the velocity of one of the balls, but keep the direction of motion. The result is that we lower the total kinetic energy of the system, since one of the balls has less kinetic energy than before. When we look to the total momentum of the new system, we observe that the system has gained netto momentum. The momentum of the first ball does not longer neutralize the momentum of the second ball, since the magnitudes of both velocities are not longer equal. Conclusion: the second system has less kinetic energy than the first, but has more momentum. If we go back from system 2 to system 1 we have an example of having more kinetic energy, but less momentum. I hope this answers your question Kjell

A collision in which kinetic energy may be transferred between the colliding particles but the total kinetic energy remains the same?
This is called an elastic collision. In this case both momentum and kinetic energy is conserved.
How is kinetic energy and momentum similar?
Answer #1:Kinetic energy is the energy possessed by an object due to its movementor motion. Momentum on the other hand, is the quantity of motion of anobject that is a product of its mass and velocity.====================================Answer #2:Kinetic Energy = 1/2 M V2kg-m2/s2 (Newton-meter = Joule)Momentum = M V kg-m/s (Newton-second)Numerical Difference = (1/2 M V2) - (M V) = (M V) x (1/2V -1) .
Can a body have kinetic energy with out having momentum?
No.
What does a vehicle's momentum depend on?
Kinetic Energy
What does not have the same units as the others Kinetic Energy Momentum Potential Energy or Work?
momentum
Why do you need momentum with kinetic energy?
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.
What is the difference between thermodynamic and kinetic stability?
Kinetic - how quickly something reacts.Thermodynamic - the energies required.
An object that has linear momentum must also have?
Momentum. The formula for kinetic energy is: KE = .5 * m *v^2 The formula for momentum is: p = m * v If an object has kinetic energy, then both mass and velocity are non-zero, which implies that the momentum is also non-zero.
How does the kinetic energy of a body change if its momentum is halved?
Since momentum is proportional to the velocity, half the momentum means half the velocity (and therefore half the speed). And since kinetic energy is proportional to the SQUARE of the speed, half the speed means 1/4 the kinetic energy.
