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.

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.
Does an object with momentum always have energy?
Not if it's potential energy. Only objects with kinetic energy have momentum.
Can an object have kinetic energy but no momentum?
No. To have kinetic energy, it must have both mass and velocity; the expression is Ek = 0.5mv2. To have momentum, something must also have mass and velocity; the expression for this is p = mv. Hence , if something has kinetic energy, you know it has momentum, and you can actually derive one from the other (provided you know the velocity); p = 2Ek/v.
Energy in the form of motion?
The energy of motion is called kinetic energy.
How is kinetic energy formed?
Kinetic energy is a form of energy that comes from motion. Therefore any moving object (that has a mass!) has kinetic energy. For kinetic energy to be produced, a force must act upon an object to give it an acceleration, to put it in motion. The simplest case is the conversion of potentiel energy to kinetic energy. When an object is far from its "normal" standing position (in this case the ground), it is said to have potential energy. When this object is attracted by the force of gravity, its potential energy is slowly converting into kinetic energy because the objet keeps on accelerating.
When kinetic energy doubled what happens to momentum?
Momentum increases
What does not have the same units as the others Kinetic Energy Momentum Potential Energy or Work?
momentum
Can a body have kinetic energy with out having momentum?
No.
What does a vehicle's momentum depend on?
Kinetic Energy
What is the energy during momentum?
There is no "energy during momentum". A moving object has both non-zero momentum, and non-zero kinetic energy.
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
How does kinetic energy change when the momentum is doubled?
energy is quadrupled
Which factor provides kinetic energy of an electron?
Kinetic energy is another name for scalar energy. Kinetic energy is provided by the vector energy cmV=cP, the momentum energy. Momentum is a vector and Momentum energy cP is also a vector, a vector energy. This Momentum Energy gives the velocity V and speed v and thus the "kinetic energy". The electron vector energy is cmV=cP and and the scalar energy is vp ! it is clear that te sclar energy vp=mv2 is much smaller than the vector energy cVm. the so-called kinetic energy is vp/2 = 1/2 mv2. kinetic energy is a product of the vector energy cmV, no Velocity , no kinetic energy.
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.
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) .
Why is radiant energy kinetic energy?
Light is made up of particles (called photons). They have both kinetic energy and momentum.
A collision in which the total momentum and kinetic energy remain constant?
Kinetic energy is only conserved if the collision is elastic. All other collisions will have some loss of kinetic energy even when momentum is conserved.
